Question

What is the relation between 1 Rad, 1 Rem and 1 R?

(a) 1 Rad ≈ 1.5 Rem ≈ 1000 R

(b) 1 Rad ≈ 10 Rem ≈ 1.8 R

(c) 1 Rad ≈ 1 Rem ≈ 1 R

(d) 1 Rad ≈ 10 Rem ≈ 100 R

The question was posed to me during an interview for a job.

I need to ask this question from Diathermy, Measurement of Radiation, Dose and its Calculations in chapter Radiation Therapy of Clinical Science

Answer 1

Right option is (c) 1 Rad ≈ 1 Rem ≈ 1 R

Easy explanation: All three units have almost the same values and they all are units and doses of radiations. Rad stands for radiation absorbed dose and it measures the radiation absorbed by the tissues of the body. Rem is radiation equivalent and it measures the biological damage caused by different types of radiation.R is for Roentgens and is used as a unit for X – Rays.
