Ionizing radiation should not be considered unequivocally harmful: in some cases, it can be of vital importance and be beneficial, for example, when diagnosing diseases with X-rays, CT and MRI, radiologist Evgeny Khmelevsky said. According to the specialist, it is safe to say that the benefits of diagnostic and therapeutic procedures such as X-rays, MRIs and radiotherapy are many times greater than the possible harms. However, all these procedures should be carried out only if there are indications: doing a CT scan every month is not recommended. If there are indications, neglecting modern research methods can be extremely dangerous - sometimes fatal, the doctor warned. According to him, scientists are now studying the benefits of ionizing radiation on the germination of seeds, as well as studying the formation of cell protective properties when exposed to high doses of radiation after prior exposure to low doses of radiation. The specialist also noted that it cannot be unequivocally stated that the minimal radiation doses a person may receive in everyday life do not lead to any adverse effects, as the limits of teratogenic and oncogenic effects of radiation on the organism have not yet been determined.
