NUCLEAR SAFETY AT HANDLING WITH THE RADIOACTIVE WASTES CONTAINING NUCLEAR MATERIALS
The wastes originate during uranium mining and production of uranium concentrate, isotopic enrichment, nuclear fuel production, uranium dioxide-to-uranium hexafluoride conversion, processing of radionuclides generated in the NPP core as a result of the neutron capture and nuclear heavy nuclide fission as well as a result of neutron activation of some nuclides contained in the moderator, coolant or structural materials.
Purpose ::: Surveillance after orchiectomy alone has become popular in the management of clinical stage I nonseminomatous germ cell testicular tumors (CSI NSGCTT), and adjuvant chemotherapy has been accepted in high-risk CSI NSGCTT. Because of the late toxicity of standard radiotherapy in CSI testicular seminoma (SGCTT), this therapeutic approach has been accepted also in the management of CSI SGCTT. In the current study, we analyzed single-center experience with risk-adapted therapeutic approaches (active surveillance and adjuvant chemotherapy) in patients with CSI SGCTT.
