Abstract  

The analysis of99Tc was carried out in filter, peat and rainwater samples. A solvent extraction technique was used to separate Tc from them, where tributylphosphate was the extracting agent. Radiochemical yield was obtained by using99mTc as an internal tracer. A typical value of 60% was found for it. However, problems encountered in its determination are discussed in the text. Additionally, rainwater samples were analyzed for137Cs. This was adsorbed in ammonium phosphomolibdate. Radiochemical yield was obtained by using134Cs as an internal tracer.
