Question

A standard treatment to kill pathogens in ground beef is to irradiate it with high-energy electrons. In a typical treatment, 1.9 kg of beef receives 4.5 kGy of radiation in 41 s .

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 0.76 of that of water. (Water's specific heat is 4190 J/kg⋅C∘.)

Answer 1
