One industrial application of radiation is to kill microbes in food, giving the food a longershelf life and allowing longer storage without refrigeration. (a) Which isotope is usually used for this purpose and why? (b) Calculate the increase in temperature of 200 kg of strawberries that are irra-diated with gamma rays to a dose of 500 Gy. Assume there was no means to cool theberries during the irradiation and that the density and heat capacity of a strawberriesis the same as water; 1 g/cm3 and 4.184 J/g◦C, respectively.
