EFEITO DA CALDA SULFOCÁLCICA SOBRE O ÁCARO Tetranychus mexicanus (MCGREGOR, 1950) EM CITROS

The effects of the fallout from the nuclear reactor accident at Chernobyl have been monitored at various sites to Greece. Here we present the first estimates of gamma dose rates, an essential parameter in the dating of archaeological materials by thermoluminescence (TL) and ESR methods. The dose rates are derived from the long-lived radionuclides of 137Cs, 134 Cs, 1°6 Ru and 144Ce (with t112 >-1 yr). The present dose rates vary between 30 and 60 mrad/yr, but maximum values of around 811 mrad/yr have also been recorded, for ground-surface exposures. These dose rate values must be regarded as very significant to TL and ESR dating of samples from now on and a correction factor should be applied.
