  • Radiochemical purity of technetium-99m-nanocolloid

    To evaluate the effect of heating on particle size, preparations were filtered through a 0.22 µm sterilizing membrane filter before and after 30 min of heating. The radioactivity was measured before and after the filtration. The results showed that absence of heating does not influence the apparent RCP of Tc-nanocolloid of rhenium sulphide.
