2016 Progress in Electromagnetic Research Symposium (PIERS)

The origin of ultra-high-energy cosmic rays (UHECRs) is still a mystery. Neutrinos are a fundamental element in an astrophysics puzzle. Extensive air showers generated by UHECRs contain neutrinos interacting with other particles via charged and neutral currents. Due to a very low cross-section of neutrinos and in consequence due to a very low rate of neutrino-induced events their detection is a significant...

Nukleonika > 2014 > 59 > 2 > 43-52

The main objective of ²³⁵U irradiation is to obtain the ^99mTc isotope, which is widely used in the domain of medical diagnostics. The decisive factor determining its availability, despite its short lifetime, is a reaction of radioactive decay of ⁹⁹Mo into ^99mTc. One of the possible sources of molybdenum can be achieved in course of the ²³⁵U fission reaction. The paper presents activities and the calculation...
