title: Radiological impact of composite food served at PINSTECH.
abstract: To determine radiological impact of composite food served at Pakistan Institute of Nuclear Science and Technology (PINSTECH) on its worker, cooked meals were collected during 2000-2007 and analysed by gamma and beta radiometry techniques for naturally occurring radionuclides and fission fragments. The only measurable radionuclide was naturally occurring (40)K. Its activity range was 40+/-1.5 to 182.4+/-3.8 Bq kg(-1) with cumulative average value of 89.4+/-35.1 Bq kg(-1). Based on annual meals taken by the worker in cafeteria, the measured value gives committed effective dose of 74 microSv and estimated cancer risk factor of 1.5 x 10(-4) that is a minor fraction of the total risk of 5 x 10(-3). It depicts that food served at PINSTECH cafeteria is radiologically safe for consumption.
