“…The international recommendations of quality factor depend on linear energy transfer (LET) of radiation and increases from 1 to 20 1- 3 . LET, on the other hand increases from 3.5 to 200 keV/µm 4 . The quality factor assigned for x-rays, gamma rays and electrons as 1, irrespective of the energy.…”

The quality factor for x-rays, gamma rays and electrons assigned as one need to be revised. It is observed that as the energy decreases, mean lethal radiation dose (Do)decreases as well and become more potent. It is therefore proposed that radiation quality in biological systems should be assessed in the mitotic phase of the cell cycles. Furthermore, based on the mean lethal radiation dose within specific energy range, an appropriate quality factor of x-rays, gamma rays and electrons should be assigned.

“…To assume that 25 MV x-rays produce the same biological effect as 20 kV is based on hypothetical assumption and no data is provided as how we have arrived at the quality factor of 1. The accepted quality factor according to Filyushhin 4 has no radiobiological basis and certainly need a revision.…”
