NUCLEAR MEDICINE PRACTICE AND RADIATION DOSES TO PATIENTS
IN INDIA : PART II. RISK RELATED RADIATION DOSES TO PATIENTS
The decay of radionuclides following their
administration to patients leads to deposition of energy
within various organs, tissues, cells and subcellular
fractions. The calculation of the absorbed dose, has
therefore, been an important activity in nuclear medicine
and forms the primary basis of any form of risk assessment
for diagnostic nuclear medicine 'procedures1-2. Besides
the health risk(s) involved, such dose estimation also helps
to determine the amount of radionuclide that should be
administered to patients during routine procedures. Some
dosimetric quantities and concepts are given in the
Appendix.
The Medical Internal Radiation Dose (MIRD)
Committee of the American Society of Nuclear Medicine
has developed the method of estimating organ absorbed
dose which is generally referred to as MIRD Scheme3.
This system ofdose estimation assumes that the distribution
of radionuclide in the organ/tissue of interest is uniform
and that particulate radiation (beta and other electrons)
are isotropic in their distribution and have ranges that
are larger relative to typical cell diameters. Such conditions
may not be always strictly true4, however, for most of
the dosimetric purposes, MIRD scheme has given valuable
data On absorbed dpse estimation in most of the clinical
situations. For the present study, the age-dependent

absorbed dose coefficient values (S-factor values) as given
in ICRP Publications5-6 for various radiopharmaceuticals,
have been utilized.
Effective dose (ie risk related radiation dose) esti­
mation requires reliable information on S-factor values
for all the organs and radiopharmaceuticals of interest,
suitable tissue/organ weighting factor values and appro­
priate procedures for the dose estimation. There have been
only marginal changes in the S-factor or absorbed dose
coefficient values for the organs/tissues of interest for
most of the radiopharmaceuticals, with a few exceptions
like when a new organ or biokinetic model was accepted7
or when some discrepancies in values of basic data had
occurred’-’. However, significant modification had been
effected in the tissue weighting factor values and in the
methodology ofeffective dose computation from the earlier
recommendations of the International Commission on
Radiological Protection10. For the present study, the values
of tissue weighting factor as given in ICRP 1990" have
been used.
The effect of the new tissue weighting factor values
on the effective dose (earlier known as effective dose
equivalent) due to a large number of radiopharmaceuticals,
has been studied extensively12'19 and it was observed that
in case of radiopharmaceuticals-used in India, either the

effective doses had remained unchanged or had become 1016 % lower than the previous values. On further scrutiny
some discrepancies in the procedures recommended11 for
effective dose estimation, were noticed. These discrep­
ancies and the problems that resulted by following these
recommendations have' been highlighted20,21 and a new
modified methodology suggested22. The modified meth­
odology was further updated incorporating subsequent
ICRP recommendations23 and used for effective dose
estimations. The salient features of the methodology are:

(i) Wherever the mean absorbed dose coefficients to an
organ/tissue and the explicit value of tissue weighting
factor assigned to it, are available, the contribution of
the organ/ tissue to the effective dose is computed in the
standard procedure recommended in ICRP 1990”.
(ii) Since relative masses of the walls of the upper large
intestine (ULI) and lower large intestine (LLI) are inde­
pendent of age, the equivalent dose to colon - Hcolon is
given as in ICRP 199523.

medicine procedures. The amount of radioactivity used
for an investigation varied within wide limits from cen­
tre to centre, however, the amounts seldom exceeded the
limits set by ARSAC26. The list of radiopharmaceuticals
and the range of radioactivity used for commonly per­
formed imaging procedures in the country is given in
Table I. Risk related radiation dosimetry was carried out
for these radiopharmaceuticals.

(iii) Tissue weighting factor value assigned to gonads is
allotted to testes or ovaries which ever is getting higher
equivalent dose (ICRP 1995)23.
(iv) Tissue weighting factor values assigned to the oe­
sophagus and skin (for which age dependent absorbed
dose coefficient for many radiopharmaceuticals used in
India are not available) are considered to be part of the
remainder.

(v) The remainder tissue weighting factor is thought of
as consisting of 0.0511 plus 0.05 (weighting factor value
of oesophagus) plus 0.01 (weighting factor value of skin).
Thus the total remainder tissue weighting factor is 0.11
which is to be apportioned as per guidelines (ICRP 1995)23.
Half the total remainder weighting factor ie 0.055. is as­
signed to any of the remaining organs/tissues that re­
ceives the highest equivalent dose of all organs, and the
other half to the mass average committed equivalent dose
in the rest of the remainder tissues and organs.
Using this methodology, the effective doses for a large
number of radiopharmaceuticals were calculated18,24,25

Risk Related Radiation Dosimetry
About 35,000 nuclear medicine in vivo investigations
were found to be performed per month at 58 centres lo­
cated in 28 cities in the country. Investigations varied
from simple thyroid uptake tests to sophisticated nuclear
72

Age dependent effective dose coefficients calculated
by indigenously developed modified dosimetry approach
for the radiopharmaceuticals of interest are presented in
Table II. It shdws that most of the nuclear medicine

investigations employing Tc-99m and Tc-99m based
radiopharmaceuticals result in effective doses to patients
of the order of millisievert or less. As different investi­
gations employ different amounts of radioactivity, there­
fore, for calculating effective dose to the patient, these
effective dose coefficients have to be multiplied by the
actual amount of radioactivity (in MBq) used in the
particular nuclear medicine investigation. The Table also
shows that as the age of the patient increases, the effec­
tive dose coefficient decreases. This implies that for the
same amount of administered activity, a one year old
child may receive a higher effective dose (3 to 10 times)
and therefore, may be at a higher risk of radiation detri­
ment in comparison to an adult. The situation warrants
greater care while carrying out nuclear medicine inves­
tigations in children.

A comparison has been made (Table III) of the ef­
fective dose coefficient values as calculated by the modi­
fied methodology and as given by ICRP6 for adults for
radiopharmaceuticals used in India. The Indian values
of effective dose coefficients are higher by about 10%
(5-20%) than the values given by ICRP6. One of the rea­
sons for lower ICRP values may be the ambiguous man­
ner in which the remainder of tissue weighting factor
and doses to remainder tissues or organs are treated. The
values based on the modified method are in closer agree­
ment with the ICRP values of 1987s where the proce­
dure for dose computation is more straight forward.

Each nuclear medicine diagnostic investigation re­
sults in different effective dose to patients. In general,
investigations employihg Tc-99m and Tc-99m based

Investigation

99m based radiopharmaceuticals resulted in low radia­
tion doses, other radiodiagnostic agents specially 1-131
and 1-131 based agents imparted significant radiation doses
to patients. At most centres, the amount of radioactivity
administered to a patient, was adjusted to his/her age and
weight. In a significant number of cliifics/centres par­
ticularly those located in comparatively smaller cities,
investigations were being still carried out using 1-131
and 1-131 based radiopharmaceuticals resulting in un­
warranted high radiation doses to patients.

APPENDIX
Absorbed dose (D)^ The basic physical quantity used in nuclear medicine dosimetry is the absorbed dose. For all types of radiation, the
absorbed dose is a measure of the amount of energy from the radiation field which is deposited in unit mass of an organ or tissue. The SI unit
of absorbed dose is joule per kilogram and is called gray (Gy). The method of calculating absorbed dose in nuclear medicine has been
developed over many years by the Medical Internal Radiation Dose (M1RD) Committee of the American Society of Nuclear Medicine. In the
MIRD scheme, a body is considered to consist of source organs (ie those with significant uptake of radiopharmaceuticals) and the target organs
(ie those being irradiated by the source organs). For each pair of source and target organs, the following equation is used to calculate the
absorbed dose D (T<-S) in Gy to a target organ ‘T* from the activity in the source organ ‘S’.
D(T<-S) = A, x S (T<-S)
A( is the time-integrated, or cumulated activity, and is equal to the total number of nuclear transformations in S; and S (T<—S) is the absorbed
dose in T per unit cumulated activity in S and is referred as the S-factor which is the absorbed dose coefficient for that organ. Numerical values
of S (T<—S) or simply ‘S’ have been tabulated for large number of organs and tissues in both standard man and children for a variety of
radionuclides and radiopharmaceuticals. Age dependent ’S’ vrlues are given in ICRP publication 53 (ICRP 1987) and later in one of its
addendum (ICRP 1992).

Equivalent dose (H) : Even when the energy is equal at a macroscopic level (ie, the absorbed dose is the same) different types and energies
of radiation will produce different amounts of biological damage. To allow for this, a further quantity has been introduced. This is called the
equivalent dose, H , which is the average absorbed dose in an organ or tissue multiplied by a dimensionless radiation weighting factor, WR
that is a function of linear energy transfer (LET) of the radiation. Radiation weighting factor of 1 is assigned to low LET radiation, including
X-rays and gamma-rays of all energies. The SI unit of equivalent dose is joule per kilogram and is called sievert (Sv). Smaller unit of
equivalent doses are millisievert (mSv) and microsievert (pSv) that are one thousandh and one millionth of a sievert respectively. For almost
all the radiation used in medical imaging, radiation-weighting factor is unity, so the absorbed dose and equivalent dose are numerically equal.

Effective dose : Effective dose equivalent is the risk related parameter to describe the overall effect of non homogeneous dose distribution
(as takes place in nuclear medicine imaging), taking into account the relative radiosensitivity of each organ and tissue and is similar, in terms
of overall risks , to a uniform whole body exposure in which each organ receives an equivalent dose equal to effective dose. The Effective
dose E = E
is obtained by calculating a weighted average of the equivalent doses received by each organ or tissue in the body which
has been irradiated (where WT is the tissue weighting factor for organ T, HT is the.equivalent dose received by organ or tissue T and E WT=1).

The relationship between the different dosimetric quantities are illustrated in the flow chart

‘Organs or tissues which are at higher risk (or are more sensitive to radiation detriment) are given higher tissue weighting factor. The
values of tissue weighting factor are given in Table A. The different dosimetric quantities used in nuclear medicine and their conversion from
one unit system to another is given in Table B. Effective dose is also expressed in sieverts (Sv), millisieverts (mSv) and microsieverts (pSv).
Effective dose as defined by the International Commission on Radiological Protection", provides a possibility of expressing the radiation risk
to patients undergoing different radiodiagnostic procedures by means of a single figure.

Action of cisplatinum on some unicellular organisms.

Publications

A study was conducted to investigate the mode of action
of cisplatinum on unicellular ciliate species in order to
understand the action of this drug on eukaryotic cells and
some aspects of its metabolism. Several different species of
genus Stylonchia collected from wild habitat were treated with
anticancer drug, cisplatinum in the dose of 150 pg/ml for 2 h.
Studies on macronucleus and micronucleus were carried out
to study the mechanism ofaction ofthe drug. Different species
ofthe unicellular ciliate protozoa viz isolated from wild habitats
exhibited variable sensitivity towards the antitumour drug
cisplatinum. Intracellular quantitative measurements of
platinum in post-treatment resistant cells showed that higher
resistance was not due to poor metal uptake; these cells showed
comparatively higher uptake.' Likewise, the germ line
micronucleus of these cells was highly vulnerable to genetic
damage in comparison to the somatic nuclei. The germ line
nuclei bound at least 3 times more of platinum when cells
were treated in situ.The DNA lesions in the micronucleus
caused by extremely low platinum dosages were detrimental
to the completion ofmeiosis and formation ofa new functional
somatic-macronucleus. DNA characterization of platinum
damaged micronuclei showed unusual fragmentation to low
mol. wt. components. Such damage was irreversible leading
to the loss of micronuclei and production of amicronucleate
strains. It appeared that micronuclear components like non
histone chromosomal proteins facilitate higher platinum
binding leading to fragmentation ofhigh mol. wt micronuclear
DNA.

Evaluation ofthe effectiveness of brief in-patient family
intervention vs. out-patient intervention for mentally
retarded children.

A prospective study was carried out-on mentally
retarded children to evaluate the effectiveness of brief in­
patient and out-patient family focussed interventions
(developed in-house) in terms oftheir impact on the child’s
development and behaviour, and family adaptation
(perceived stress and coping). The components of the
intervention included medical measures, family
orientation, general parenting measures, and parent
training. Outcome variables studied included child
variables (intellectual/adaptive functioning and presence
and severity of problem behaviour) and family variables
(self report and observer rated stress in families and level
of family adaptation).
A total of 157 mentally retarded children of either sex
(75 in the in-patient group and 82 in the out-patient group)
from low socio-economic group (both rural and urban) and
TI

with moderate to profound degree of mental retardation
were recruited for the study. Children who had already
undergone major intervention, those with severe hearing
or vision impairment which was more disabling than the
mental retardation and children with progressive neurologic
disorders were excluded from the study. Thirty three (44%)
children/families is the in-patient and 47 (57%) in the out­
patient group could complete one year of follow up.

Improvements or gains were noted on all outcome
measures to a varying extent in both the groups. The gain
in the child adaptive functioning was more pronouned in
the in-patient group (10 points) as compared to the out­
patient group (4 points). Problem behaviour came down
by 55-60%, family stress reduced by 27-35% and family
adaptation was improved by 30% in both the groups.
Maximum gains occurred during the first 3-6 months of

follow up and subsequently remained stable over the
remainder of the follow up period. There were no major
effects of age, sex, and residence on outcome.

It is therefore concluded that it is possible to formulate
and test effective family focussed interventions in mental
retardation which are suited for Indian conditions and such
inerventions will produce long-lasting and significant
improvements in both children and their families.
