A 65.0-kg worker at a nuclear plant is exposed for 5.00 minutes to 1.00 mCi of beta radiation from 90Sr, each with energy of 0.546 MeV. (a) How many beta radiations does he receive? (b) If 75.0% of the radiation energy is absorbed, what is the total radiation energy (in Joule) absorbed by the worker? What is the radiation dose in gray (Gy) and rad (radiation absorbed dose)? (c) Assuming that the beta radiation has RBE of 0.95, express the...
A particle of rest energy 140 MeV moves at a sufficiently high speed that its total relativistic energy is 301 MeV. How fast is it traveling? (Enter your answer as a multiple of c. (All answers posted so far have been wrong)
Phosphorus-32 (P-32) is used in nuclear medicine as therapeutic
agent in the treatment of several diseases. P-32 has a half life of
14.3 days and decays directly to its ground state by emitting a
beta-minus particle. The decay table for P-32 is given. There are
no excited energy states or other radiation emitted during this
decay; therefore, P-32 is referred to as a "pure beta emitter.
A P-32 sample is prepared in the manufacturing site with
an initial activity of...

1. At time t = 0, a sample of radioisotope Physiconium has activity 4096 counts/second (Bq) and half-life 30 minutes. What is the expected activity after 2 hours, in becquerel? 2. High energy protons are used for some special radiation therapy situations. The protons have mean energy = 1 MeV, and 4 million particles are absorbed a region of the brain which has mass 0.1 kg. Find the absorbed dose for the brain region, in milligray. 1 eV =...
