A tumor of 120 g absorbs a total of 1.7 J of energy. Determine the absorbed dose in rads.
I got 1417 rad, am I correct?
Thanks!
To determine the absorbed dose in rads, you need to know the energy absorbed and the mass of the tissue.
The absorbed dose (D) is defined as the amount of energy absorbed per unit mass:
D = Energy absorbed (J) / Mass of tissue (kg)
Given that the tumor absorbs 1.7 J of energy, and its mass is 120 g (or 0.12 kg), you can calculate the absorbed dose as follows:
D = 1.7 J / 0.12 kg = 14.17 J/kg
Now, to convert this to rads, you need to use the conversion factor:
1 rad = 0.01 J/kg
Multiplying the absorbed dose by the conversion factor:
D in rads = 14.17 J/kg * 1 rad / 0.01 J/kg = 1417 rad
Therefore, your answer of 1417 rad is correct.
