Ground beef may be irradiated with high-energy electrons from a linear accelerator to kill pathogens. In a standard treatment, 1.7kg of beef receives 4.4 kGy of radiation in 50s .
Part A How much energy is deposited in the beef?
Part B What is the average rate (in W) of energy deposition in the beef?
Part C Estimate the temperature increase of the beef due to this procedure. The specific heat of beef is approximately 0.74 of that of water.
About 12% of your body mass is carbon; some of this is radioactive 14^C, a beta-emitter.
If you absorb 100% of the 49 keV energy of each 14^C decay, what dose equivalent in Sv do you receive each year from the 14^C in your body?
