background: the south-west coast of india is known to have very high levels of natural background radiation due to the monazite beach sand. uranium is the heaviest trace element found in all terrestrial substances at varying levels with chemical and radio toxicities. it supports several short-lived radioisotopes in its decay series including radium. uranium in drinking water is important in ter...

Thermal history and apatite fission-track ages were determined for the Kaleybar, Razgah and Bozqush alkaline intrusions which display Eocene-Oligocene stratigraphic age. These subduction-related intrusions are located in the Alborz-Azarbaijan magmatic belt which is characterized by a Paleogene magmatic flare-up associated with extensional/transtensional tectonism. The mean of Uranium content an...

This paper reports the measurement of high energy neutron component (E > 50 MeV) carried out at the Indus-1 (450 MeV) and Indus-2 (2.5 GeV) electron accelerators (RRCAT, Indore, India). The study is based on the registration of neutron induced fission fragments from bismuth radiators in the adjoint solid polymeric track detectors. These bismuth fission detector (BFD) stacks are exposed at the i...

The simple and effective technique of fission track etch has been applied to determine trace concentration of uranium in human blood samples taken from two groups of male and female participants: leukemia patients and healthy subjects group. The blood samples of leukemia patients and healthy subjects were collected from three key southern governorates namely, Basrah, Muthanna and Dhi-Qar. These...
