Monitoramento das Doses de Inativação Esporular, radiação UV-B e temperatura no Observatório Espacial do Sul, São Martinho da Serra, RS, no período 1999 - 2006

In this work an overview of UV-B, spore dosimetry and temperature monitoring at the Southern Space Observatory, in São Martinho da Serra, south of Brazil from 2000 to 2006 is reported. Using Bacillus subtillis TKJ 6312 (uvr,spl) as biosensor of solar radiation in form of spore inactivation doses, Brewer measurements of UV-B and temperature, profiles of seasonal variations were observed. In this context, the impact of the solar radiation and temperature on biological systems has been studied. The temperature, UV-B and SID varied about 40%, 80% and 92% along of the analyzed period. The principal perturbations of the temperature on the spore inactivation doses are observed in the end of Spring and in Summer, indicating an influence of about 11% on the absolute values.
