Gamma rays may be used to kill pathogens in ground beef. BD One irradiation facility uses a ${ }^{60} \mathrm{C}$ source that has an activity of $1.0 \times 10^6 \mathrm{Ci} .{ }^{60} \mathrm{C}$ undergoes beta decay and then gives off two gamma rays, at $1.17$ and $1.33 \mathrm{MeV}$; typically $30 \%$ of this gamma-ray energy is absorbed by the meat. The dose required to kill all pathogens present in the beef is 4000 Gy. How many kilograms of meat per hour can be processed in this facility?
