| Abstract: | Since ozone effectively absorbs solar UV radiation, it is generally accepted that any depletion of the ozone layer will increase the level of UV radiation reaching the ground and may have a deleterious effect on life on the earth. Based on the biological action spectra and total UV-B radiation in the atmosphere, we have calculated the effective UV-dose for DNA, erythema, and plant at different seasons in the last decade, and forecasted their future changes in Beijing area. Computation results indicate that the maximum of biologically effective radiation dose at noontime is in July and the minimum is in January. From 1980 to 1989 biologically effective radiation dose have increased in January, April and October, while in July the trend of radiation dose is not in evidence. For 1 % reduction of ozone concentration, the radiation amplification factor (RAF) for DNA, erythema and plant are 2.3, 2.3, and 1.4,and for 30% reduction of ozone concertration the RAF for DNA, erythema and plant are 4.2, 4.0 and 2.1,respectively. |
