(a) Due to the high protein and carbohydrate content of the cells

(b) Due to the higher energy of the cells

(c) Due to the low energy of the cells

(d) Due to the high oxygen content of the cells

This question was posed to me in homework.

Asked question is from Radiation Therapy topic in division Radiation Therapy of Clinical Science

Answer 1

Correct answer is (b) Due to the higher energy of the cells

To elaborate: If a cell is fast dividing, then it produces and consumes higher energy. Radiations are also a form of energy, they are electromagnetic waves and have the ability to ionize and penetrate. Thus, a high energy cell my end up absorbing the radiations and then end up suffering damage.
