SOLAR RADIATION EFFECT ON THE MORBIDITY OF MALIGNANT SKIN NEOPLASMS AND MORTALITY FROM THEM

Abstract

We studied the solar radiation effect on the morbidity of malignant skin neoplasms and mortality from them in the Irkutsk region population as one of risk factors. It is established that population’s morbidity rates of skin melanoma from 3.3 ± 0.3 to 5.0 ± 0.4 per 100 thousand and other malignant skin neoplasms from 26.0 ± 0.9 to 32.4 ± 0.9 per 100 thousand increased; the mortality rates from them became respectively from 1.6 ± 0.2 to 1.8 ± 0.2 per 100 thousand and from 0.2 ± 0.1 to 0.5 ± 0.1 per 100 thousand in the region during the 2007–2017 period. According to the results of the correlation-regression analysis we found the effect on the morbidity of malignant skin neoplasms for such parameters as direct solar radiation on a horizontal surface, total solar radiation, radiation balance and longwave radiation balance; direct and measured solar radiation influenced mortality from malignant skin neoplasms. To reduce the morbidity of malignant skin neoplasms of the Irkutsk region population, it is necessary to widely educate the population about the dangers of excessive exposure to ultraviolet radiation and inform about local levels of solar radiation according to quality monitoring data.
