A radiation worker stands 35 cm away from a radioactive source of 30 mCi (11.1 GBq) 9mTc (k, for 99mTcis 0.80 R-cm/mCi-hr at 1 cm or 18.0 µGy-m?/ GBq-hr at 1 m). Calculate the exposure value received bythe worker while standing for 1 hr near the source. The isotop half-life is 6 hours.

How many Gy of exposure is needed to give a cancerous tumor a dose of 40 Sv if it is exposed to acfivity?
(a) Background radiation due to 226Ra averages only 0.01 mSv/y, but it can range upward depending on where a 226Ra in the 80.0kg body of a man who receives a dose of 2.50mSv/y from it, noting that each 226Ra decay emits a 4.80MeV particle. You may person lives. Find the mass of neglect dose due to daughters and assume a constant amount, evenly distributed due to balanced ingestion and handily elimination. (b) Is it surprising that such a small mass could cause a measurable radiation dose? Explain.
