 note = {The work describes the uptake, retention/biological elimination and organ/tissue distribution of Cs-137 by Japanese Catfish (Silurus asotus Linnaeus) under laboratory conditions. The fish
were divided into three groups viz. large, medium and small based on their size and age and
reared into the Cs-137 spiked water. The accumulated Cs-137 concentration in the whole body
of the live fish was measured at certain intervals up to 60 days. A significant accumulation
of Cs-137 was found but a steady state accumulation of the nuclide was not achieved by the
end of the experiment. 
To determine the effective half-life of Cs-137 in the fish species, the contaminated fish were
transferred and reared into the non-contaminated host water. The concentration of the remaining
Cs-137 in the whole body of the live fish was measured up to 66 days. The average effective 
half-life of Cs-137 in the fish species was found to be -142 days for all size of fish.
The uptake rate and retention capability of juvenile fish were found to be higher and therefore, more susceptible to Cs-137 than adult and old fish and could be an important source
of Cs-137 in the human food chain. The distribution of Cs-137 in different organs/tissues of
the fish were determined. Accumulation of Cs-137 in muscle/flesh of the fish was found to be
-75% of whole body accumulation., International Conference on Isotopic and Nuclear Analytical Techniques for Health and Environment},
