Recently, measurement of lymphocyte transformation by the ~3H-Tdrincorporated method has been reported. This method is simpler, more sensitive and more effective than others, and many samples can be determined at the same time. The method is based on the consideration that the physicochemical quality and incorporated biological great molecular behaviour of ~3H-TdR and ~1H-TdR are regarded as similar. However the mass of ~3H is treble that of ~1H. So they are different in chemical kinetics and thermodynamics. Further, the bio-展开更多

INTRODUCTION The prevailing routine TL dating method is actually a dose dating. The TL of a sample must first be transferred to the absorbed dose and divided by the annual dose of the sample (estimated by using radioactivity measurement and chemical analysis) before the date can be calculated. This method is not the whole TL dating. Even if all measurements are made by using TLD, it is yet a dose dating. Dosimetry is a展开更多

Although searching for its effective antidotes has been of world-wide interest, all hitherto reported chelating agents for it are of no practical value owing to their low efficacy or high toxicity.
