Materials and Methods: In this research, absorbed dose to skin and depth dose from the skin surface have been calculated for 90Sr/90Y, 147Pm, 32P beta emitter radioisotopes by using input parameters: activity of source, ...

Activity concentration of the radionuclides presented in liquid effluents has been evaluated in IFIN-HH laboratories. Gamma-ray spectrometry analyses have been performed for liquid and residue samples, and gross beta activity has been evaluated only for residue samples. Co, Cs, Eu, Eu and Ag radionuclides have been found with a higher concentration in residue samples. Taking into account previo...

Radionuclide injury to the lung has been studied in rats, hamsters, dogs, mice and baboons. Exposure of the lung to high dose levels of radionuclides produces a spectrum of progressively more severe functional and morphological changes, ranging from radiation pneumonitis and fibrosis to lung tumors. These changes are somewhat similar for different species. Their severity can be related to the a...

In many applications, the radionuclidic purity of a radioactive substance is crucial property. It involves, for example, production radiopharmaceuticals or reference standards used in metrology. However, identification admixtures not straightforward certain nuclides. The paper presents technique determination radionuclide impurities mixtures pure beta-emitting proposed method based on compariso...

Yttrium-90 has been described as one of the best radionuclides for tumor therapy when chelated to tumor-associated antibodies. This evaluation is based on the superior properties of this radionuclide (suitable half-life, pure beta-ray emitter of intermediate energy, stable daughter, and suitable chemical properties) and because it is available as a radionuclide generator product by decay of its...
