Canadian deuterium uranium (CANDU) pressurized heavy-water reactors produce 14C by neutron activation of trace quantities of nitrogen in annular gas and reactor components (14N(n,p)14C), and from 170 in the heavy water moderator by (170(n,a)14C). The radiocarbon produced in the moderator is removed on ion exchange resins incorporated in the water purification systems; however, a much smaller ga...

Nuclear power plants alone are not a proliferation risk. Without enrichment or reprocessing capabilities, power-reactor fuel, whether fresh or spent, cannot be used for the production of nuclear weapons. There are various ways, however, in which reactor projects and related nuclear fuel-cycle facilities could be used to further a nuclear-weapons development programme. This chapter describes the...

I discuss a few of the recent developments in nuclear reactions at very low energies with emphasis on the role of radioactive beam facilities.

A National Cancer Institute (NCI) survey published in the Journal of the American Medical Association, March 20, 1991, showed no general increased risk of death from cancer for people living in 107 U.S. counties containing or closely adjacent to 62 nuclear facilities. The facilities in the survey had all begun operation before 1982. Included were 52 commercial nuclear power plants, nine Departm...

Introduction Tritium (3H) in the natural environment is derived from natural or anthropogenic sources and can be used to estimate human radiation exposure around nuclear fuel reprocessing facilities. Elevated concentrations of 3H in the environment are generally associated with its production at nuclear facilities and exposure of local populations can be a public concern. The concentration of c...

BACKGROUND In April 2010, the U.S. Nuclear Regulatory Commission asked the National Academy of Sciences to update a 1990 study of cancer risks near nuclear facilities. Prior research on this topic has suffered from problems in hypothesis formulation and research design. OBJECTIVES We review epidemiologic principles used in studies of generic exposure-response associations and in studies of sp...

bangladesh is one of the smaller states in asia. but it has a long and rich history of nuclear medicine for over sixty years. the progress in science and technology is always challenging in a developing country. in 1958, work for the first nuclear medicine facility was commenced in dhaka in a tin-shed known as ‘radioisotope centre’ and was officially inaugurated in 1962. since the late 50s of t...
