People in some areas of Ramsar, a city in northern Iran, receive an annual radiation absorbed dose from background radiation that is up to 260 mSv y−1, substantially higher than the 20 mSv y−1 that is permitted for radiation workers. Inhabitants of Ramsar have lived for many generations in these high background areas. Cytogenetic studies show no significant differences between people in the high background compared to people in normal background areas. An in vitro challenge dose of 1.5 Gy of gamma rays was administered to the lymphocytes, which showed significantly reduced frequency for chromosome aberrations of people living in high background compared to those in normal background areas in and near Ramsar. Specifically, inhabitants of high background radiation areas had about 56% the average number of induced chromosomal abnormalities of normal background radiation area inhabitants following this exposure. This suggests that adaptive response might be induced by chronic exposure to natural background radiation as opposed to acute exposure to higher (tens of mGy) levels of radiation in the laboratory. There were no differences in laboratory tests of the immune systems, and no noted differences in hematological alterations between these two groups of people.

The aim of this study was to investigate the effect of pre-irradiation with microwaves on the induction of radioadaptive response. In the 1st phase of the study, 110 male mice were divided into 8 groups. The animals in these groups were exposed/sham-exposed to microwave, low dose rate gamma or both for 5 days. On day six, the animals were exposed to a lethal dose (LD). In the 2nd phase, 30 male rats were divided into 2 groups of 15 animals. The 1st group received microwave exposure. The 2nd group (controls) received the same LD but there was no treatment before the LD. On day 5, all animals were whole-body irradiated with the LD. Statistically significant differences between the survival rate of the mice only exposed to lethal dose of gamma radiation before irradiation with a lethal dose of gamma radiation with those of the animals pre-exposed to either microwave (p=0.02), low dose rate gamma (p=0.001) or both of these physical adapting doses (p=0.003) were observed. Likewise, a statistically significant difference between survival rates of the rats in control and test groups was observed. Altogether, these experiments showed that exposure to microwave radiation may induce a significant survival adaptive response.

About Me
SMJ Mortazavi is a Professor of Medical Physics at the School of Medicine, Shiraz University of Medical Sciences. He has a strong background in medical physics and specializes in the biological effects of ionizing and non-ionizing radiation. He completed a postdoc awarded by the Japan Society for Promotion of Science (JSPS) at Kyoto University of Education and then joined the faculty of RUMS, Rafsanjan, where he served as Assistant/Associate Professor until 2008. He later moved to SUMS, Shiraz and served as Associate/Full Professor. He has also been a Visiting Scientist at Fox Chase Cancer Center, Philadelphia (2017-2018) and University of Wisconsin-Milwaukee, Milwaukee (2018). Mortazavi has authored over 300 Scopus-indexed papers in well-known peer-reviewed journals, covering areas such as low dose radiation, radiation protection, radiation shielding, natural radiation, space radiation/medicine, and non-ionizing radiation. His research focuses on the issue of space radiation, particularly biological protection of astronauts against high levels of space radiation in deep space missions, such as future manned journeys to Mars. He is also a member of the editorial boards of well-known journals such as the International Journal of Low Radiation (IJLR), Radiology of Infectious Diseases, and International Journal of Radiation Research (IJRR).
