Assuming that the specific heat of the body is 1 cal g^-1 degrees C^-1,

a) Plot the approximate temperature rise as a function of whole body dose ranging from 100 mGy to 10 Gy

b) What absorbed dose would correspond to a potentially lethal heat body burden, assuming that a body temperature rise of 5 degrees C (normal body temperature ~ 37 degrees C) can be lethal?

The Grey unit is a measure of energy deposited in a sample. If a 1.0 kg sample absorbs 1.0 J of energy, the sample had a dose of 1.0 Gy.

So the total energy absorbed by the body is:

Where u is measured in grey and m is the body's mass.

When a body is heated up by absorbing energy, its ...
