QUESTION_4 This problem involves the evaluation of possible internal deposition from two separate incidents. In the first case, a worker accidently enters an area with surface and airborne contamination without protective equipment and is counted immediately upon leaving the area in a whole body counter (WBC). The results are: 60c0 54mm Initial count 18 Feb 0800 160 nCi 46 nci Clothing change, recount 18 Feb 0830 171 nCi 43 nC1 Shower, recount 18 Feb 0900 148 nC: 40 nC1 End of shift, recount 18 Feb 1600 161 nCi 41 nC1 Followup, recount 19 Feb 1200 132 nci 38 nC1 Followup, recount 20 Feb 1020 3 nC1 Based on the scenario described above and the accompanying data, you are to select the best answer for each of the following conditions: Log I In a separate incident, another worker is evaluated for possible uptake of a soluble compound. The accom- panying graph represents his urinary excretion following a single intake of a soluble compound of sulfur-35. For each of the following state- ments you are to select the single most likely descriptor Percent Intake Excreted Per Day 1 1 I Days After Intake POINTS 1 C. The slope and magnitude of the first component is influenced most by the: a. b. c. d. e. individual's breathing rate and lung function. transfer of radioactivity from contaminated skin. individual's water intake and kidney function. decay of a relatively short-lived radionuclide. clearance of radionuclide from the organ of concentration. 1 D. The slope and magnitude of the second component is influenced most by the: a. b. C. d. e. decay of a relatively short-lived radionuclude. clearance of radionuclide from the organ of concentration. transfer of radioactivity from contaminated skin. individual's breathing rate and lung function. individual's water intake and kidney function.
