Abstract Development of 3 H, 14 C, 41 Ca, 55 Fe and 63 Ni radiochemical analysis methods were carried out independently by two laboratories using both inactivate activated concrete samples. Two preliminary radioanalytical procedures for the non-volatile radionuclides ( Fe, Ni) one Thermal oxidation method volatile C) developed. The difficulties in development results are discussed.

background: in order to diagnose the site of thrombi, radiolabeled streptokinase can be prepared. the radiolabeled compound can be used in imaging of thrombi in many cardiovascular diseases. materials and methods: streptokinase was successively labeled with [67ga]-gallium chloride using cyclic dtpa-dianhydride. the conjugation with dtpa was optimized for concentration, time and temperature foll...

Two deoxyglucose (DG) derivatives, (α,β)-2-deoxy-2-amino(ethylcarbamate)-D-glucose (ECB-DG) and (α,β)-2-deoxy-2-amino(1,2-dihydroxypropyl)-D-glucose (DHP-DG), were synthesized and radiolabeled successfully with [99mTc(H2O)3(CO)3]+ complex. [99mTc]-ECB-DG and [99mTc]-DHP-DG complexes were prepared (96% and 93% radiochemical purities respectively) by using 46 mCi of Na99mTcO4 in 1 mL saline. Radi...

On July 16, 1945, the Trinity nuclear test exploded in desert near Alamogordo, New Mexico. A variety of new diagnostic experiments were fielded an effort to understand detailed performance device. This paper describes a series radiochemical that designed measure efficiency and neutron fluence test. These experiments, scientists who led them, laid foundation weapons radiochemistry for decades co...
