Abstract
Radionuclide identification and measurement became essential in environmental samples (air
particulate, water,soil and all foodstuff ) after Chernobyl accident. In chemistry laboratory
scientists have already substantial experience about radioisotope analysis and some
radiochemical separation techniques. On the other hand quality control measures are necessary
to show that the analytical results are reliable. For checking the accuracy of our analytical
results, our laboratory has participated in the Technical Co-operation (TC) regional project
entitled ‘’Quality Assurance and Quality Control of Nuclear Analytical Techniques” For this
purpose, IAEA Quality Control service has sent to our laboratory 4 soil samples for
determination of 90Sr activities.
Radiostrontium was extracted from the soil with 6M hidrochloric acid and then radiochemical
separation and purification methods were applied. Solution was stored at 21 days for 90Sr-90Y
equilibrium. After 21 days, Yttrium oxalate precipitation was obtained and it was counted by
using Protean Instrument WPC 9550 Low Level Alpha/Beta Counter.
