Unformatted text preview: 9-8Radiation Doses and HazardsChap. 9A male worker at a nuclear facility receives an accidental whole-body exposureof 2.3 Gy. Describe what physical symptoms the individual is likely to haveand when they occur.Solution:The deterministic effects for a 2.3 Gy dose are found from Table 9.5 and fromthe discussion in Section 9.4.2. Specifically,.sperm will be suppressed after about 74 days for up to 2 years.nausea, vomiting, fatigue, and weakness is likely to start after 2 weeks.after 3 weeks, there will be about a 30% drop in blood cell production8. A population of 500,000 around a nuclear facility receives an average whole-body dose of 0.5 rad as a result of an accidental release of radionuclides. (a)Estimate the collective gonad dose received. (b) Estimate how many childrensubsequently born would experience significant hereditary defects as a resultof this exposure to their parents. (c) Estimate how many such defects wouldoccur naturally in the absence of this accidental exposure. (d) Estimate theoccur naturally in the absence of this accidental exposure....
