Document Summary
Ozone depletion and human health increase risk of skin cancer southern most regions, the risk has increased drastically. Most personal exposures to uvr occur from: outdoor activities in the sun. Work or recreational activity, greater exposure to radiation risk of reaching higher doses of uvb throughout their lifetime. Possible interactions between climate change and ozone depletion. Predicted higher ambient temperatures in summer due to global warming. E. g. study on risk in children in the uk and the possibility of developing skin cancer. E. g. : study on incidence of skin cancer in fair-skinned males and females in 10 different regions of continental usa compared with uv-b measurements cases of skin cancer and the predicted rate by the end of 2100. More pronounced if change in climate continues. At any given latitude and altitude: solar zenith angle has the most profound effect on the terrestrial uv-b readings.
