Question

Which of the following cells have a low resistance to radiations?

(a) Lymphocytes, Spermatogonia, Erythroblasts, Intestinal crypt cells

(b) Megakaryocytes, embryo, pancreatic cells, Intestinal crypt cells

(c) Lymphocytes, Spermatogonia, hepatic cells, nephrons

(d) Megakaryocytes, neurons, cardiac cells, Intestinal crypt cells

The question was asked in examination.

Origin of the question is Radiation Therapy topic in chapter Radiation Therapy of Clinical Science

Answer 1

Correct choice is (a) Lymphocytes, Spermatogonia, Erythroblasts, Intestinal crypt cells

To elaborate: According to the researches done, the more mature a cell, higher is its resistance to the radiations. Thus, Lymphocytes, Spermatogonia, Erythroblasts, Intestinal crypt cells, which are all fast dividing cells with a smaller life time, they are highly sensitive to radiation, i.e. they have low resistance to radiation.
