Radiations and radioisotopes are used in agricultural research to induce genetic variability in crop plants to develop improved varieties, to manage insect pests, monitor fate and persistence of pesticides, to study fertilizer use efficiency and plant micronutrient uptake and also to preserve agricultural produce. Use of radiation and radioisotopes in agriculture is one of the most important fi...

Radionuclide therapy has been an integral part of systemic treatment of patients with advanced and disseminated cancer for 50 years. Specific radioisotopes (b- or a-emitters) with selective concentration at sites of bone cancer damage are used in the treatment. Radioisotopes are an important addition to the armamentarium of clinicians who take care of patients with advanced cancer and painful c...

An amendment concerning the enforcement of the law on the prevention of radiation hazards due to radioisotopes, etc., and the medical service law enforcement regulations were promulgated on June 1, 2005. This amendment concerned international basic safety standards and the sealing of radiation sources. Sealed radiation sources < or =3.7 MBq, which had been excluded from regulation, were newly i...

The activation cross sections of deuteron induced reactions on natural ruthenium have been measured up to 50 MeV for production radioisotopes rhodium (105Rh, 102mRh,102gRh,101mRh,101gRh, 100gRh, 99mRh, 99gRh), (105Ru,103Ru (cum), 102Ru 97Ru 95Ru (cum)) and technetium (99mTc, 96gTc (m+), 95mTc 95gTc 94gTc,93gTc (m+)). results are compared with the predictions most common theoretical nuclear reac...

Background : Selenium-73 (T 1/2 =7.1h) and Selenium-75 (T 1/2 =119.8d) are useful radioisotopes in many research fields. The wide ranges of applications of these radioisotopes arose great interest for their production. Simultaneous production of 73 Se and 75 Se is more cost-effective and less time-consuming. Materials and Methods : 73 As (p, 3n) 73 Se and 75 As (p,n) 75 Se reactions were determ...
