The total activity of radioactive substances transported in Albania (domestic and international) during 2007 has been some thousands Ci of unsealed and solid radioactive sources, mainly 99mTc; 131I, 60Co, 137Cs, 241Am etc., by import 鈥 export procedures, and approximately over 850 type A ...

1.the state or quality of being active 2.lively action or movement 3.any specific deed, action, pursuit, etc:recreational activities. 4.(General Physics) the number of disintegrations of a radioactive substance in a given unit of time, usually expressed in curies or disintegrations per second...
These instruments enabled the rapid mixing of solutions9,12–16 but the han- dling of radioactive substances remained difficult and laborious. The use of fluorescence labels is advan- tageous for many purposes17–24 but does not allow the quantification of high-affinity interactions with dpMeteK...
was well correlated with that measured by 3H TdR incorporation assay.The data indicated that the MTT colorimetric assay is sensitive and the use of the radioactive isotope is avoidable also.It is a suitable method for the determination of the stimulating activity of hepatic stimulating substances.关...
Our own bodies contain kilograms of carbon, and it is intriguing to think there are hundreds of14C decays per second taking place in us. Carbon-14 and other naturally occurring radioactive substances in our bodies contribute to the background radiation we receive. The small number of decays per...
In order to meet radiological safety regulations for handling radioactive substances different sampling methods are used in the laboratory to measure activity such as smear samples, aerosol filters and evaporation residues. Environmental, drinking water and foodstuff samples may require the measurement of ...
Liquid scintillation counting is a method for determining the amount of one or more radioactive substances. The method is used mainly for determining beta-emitting isotopes, such as3H,14C and32P. Beta-emitting isotopes decay by emitting energy in the form of a fast electron and a neutrino. Th...
