80 kg patient is given a radioactive dose of 99Tc with the half-life 6 hours. The activity of the solution at the injection moment is A = 5.3x10 Bq. 99 Tc releases 143 keV photons and the RBE is 0.80 Sv/Gy. Assume that 40 % of the photons release from 99Tc out of the body. a) How much radiation effects the patient in 1 minute. b) How about in 6 hours? c) 99Tc is a result from the decay of 99Mo, what kind of radiation happens? 80 kg patient is given a radioactive dose of 99Tc with the half-life 6 hours.
