Mobile telephony radiation exerts genotoxic action and significantly

enhances the effects of gamma radiation in human cells

2024

Abstract. I previously reported chromosomal damage in human peripheral blood lymphocytes

(HPBLs) induced by: a) mobile telephony (MT) electromagnetic fields (EMFs)/electromagnetic

radiation (EMR), b) a high caffeine dose, and c) the combination of the two stressors. HPBLs

from the same subjects exposed to gamma radiation at doses 0.1, 0.3, or 0.5 Gy, displayed more

aberrations than those exposed to MT EMFs or the high caffeine dose in a dose-dependent

manner. When the cells exposed to these gamma radiation doses were pre-exposed to a single

15-min MT EMF exposure, the number of aberrations increased significantly more than the

sum number of aberrations induced by the individual stressors in all subjects. Thus, MT EMF

exposure at a power density ~136 times below the latest International Commission on Non-

Ionizing Radiation Protection (ICNIRP) exposure limit, apart from the fact that it is genotoxic

by itself, significantly enhanced the genotoxic action of gamma radiation. Since gamma radiation

at similar doses is applied for diagnostic and therapeutic purposes, people should be aware of the

increased risk during treatment periods. Comparison of the genotoxic action between MT EMF

and gamma radiation shows that the ICNIRP limits are, at least, ~4.5×104 times less stringent

than the limits for gamma radiation.
