Question
One problem with x-rays is that they are not sensed. Calculate the temperature increase of a researcher exposed in a few seconds to a nearly fatal accidental dose of x-rays under the following conditions. The energy of the x-ray photons is 200 keV, and $4.00 \times 10^{13}$ of them are absorbed per kilogram of tissue, the specific heat of which is $0.830 \textrm{ kcal/(kg}\cdot\textrm{C}^\circ\textrm{)}$ . (Note that medical diagnostic x-ray machines cannot produce an intensity this great.)
$3.69\times 10^{-4}\textrm{ C}^\circ\textrm{/kg}$
