Detection systems for monitoring intakes of actinides at Trombay

A variety of detection systems are currently in operation at Trombay for monitoring intakes of actinides by occupational workers of fuel fabrication/reprocessing plants. This paper describes the detection systems, their associated electronic instrumentation and performance characteristics and brings out the advantages offered by them in investigating actual cases of actinide intakes. Illustrative data for one case are presented which appeared initially to be of inhalation intake, at one stage as that of inhalation and injection intakes, and was finally identified as that of an intake by injection (i.e. through a contaminated wound) alone, thanks to the availability of various detection systems and sophisticated data analysis techniques.
