- Find the approximate radiation dose (in mSv) for 0.1 Gy exposure to thermal neutrons. (Hint: relative biological effectiveness for various types of radiation can be found in Table 32.2 in the text.) A range of answers is acceptable.Radiation a) During a workday a worker was discovered to have consumed 1/3 gallon of water contaminated with 2.5 kBq/liter of I-131. Estimate the committed effective dose equivalent (whole body) and organ (thyroid) dose to a reference person. For the whole body dose, calculate in two ways using dose conversion factors and also in relation to the ALI. Show your work. b) An investigation revealed that a worker unknowingly ingested Polonium 210 (form Y). A 24 hour fecal sample measured three months after ingestion contained 5.4 µCi Po- 210.
