Australian scientists develop device to measure cell-level radiation
Australian scientists have developed a miniature radiation detector, the size of a human cell nucleus. The detector is designed to accurately measure the amount of energy deposited by ionising radiation within a human cell nucleus allowing better understanding of radiation effects on humans, ANSTO’s on-line magazine Velocity reported this week. The technology was developed in a collaboration ...

Dangers of Nuclear Radiation
The explosion of an atomic bomb or a nuclear reactor releases high-energy radiation. This comes from nuclides, i.e. atoms, which emit energy in the form of high-energy radiation when they decay. Nuclides and high-energy radiation are also used in medicine for diagnosis and therapy. Moreover, it is often forgotten that the human body is permanently exposed to natural sources such as radon and ...

ASTM E2450 - 11 standard practice for application of CaF2(Mn) Thermoluminescence Dosimeters in mixed neutron-photon environments
1. Scope 1.1 This practice describes a procedure for measuring gamma-ray absorbed dose in CaF2(Mn) thermoluminescence dosimeters (TLDs) exposed to mixed neutron-photon environments during irradiation of materials and devices. The practice has broad application, but is primarily intended for use in the radiation-hardness testing of electronics. The practice is applicable to the measurement ...

Feds to clean site of 1976 `Atomic Man` accident
Workers are preparing to enter one of the most dangerous rooms on the Hanford Nuclear Reservation - the site of a 1976 blast that exposed a technician to a massive dose of radiation, leading to him being nicknamed the "Atomic Man." Harold McCluskey was working in the room when a chemical reaction caused a glass glove box to explode. He was exposed to the highest dose of radiation from the ...

Radioactive particles from Chernobyl disaster may be re-released by wildfires
Fires in forests contaminated by the Chernobyl nuclear accident could lead to areas of Europe and Russia being exposed to further radioactive fallout, new research has found. The study examined the spread of the fallout and the health effects on people and animals under three different scenarios: 10, 50 and 100% of the forests being burnt. The forests and fields around the site of the Chernobyl ...

ASTM F1190 - 11 standard guide for neutron irradiation of unbiased electronic components
Semiconductor devices can be permanently damaged by reactor spectrum neutrons (1, 2) . The effect of such damage on the performance of an electronic component can be determined by measuring the component’s electrical characteristics before and after exposure to fast neutrons in the neutron fluence range of interest. The resulting data can be ...

Radiation monitors continue to confirm that no radiation levels of concern have reached the united states
During a detailed analysis of four west coast RadNet air monitor filters, the U.S. Environmental Protection Agency (EPA) identified trace amounts of radioactive iodine, cesium, and tellurium consistent with the Japanese nuclear incident. These levels are consistent with the levels found by a Department of Energy monitor last week and are to be expected in the coming days. EPA’s samples ...

ASTM E2304 - 03(2011) standard practice for use of a LiF photo-fluorescent film dosimetry system
A lithium fluoride (LiF)-based photo-fluorescent film dosimetry system provides a means of determining absorbed dose to materials by the photo-stimulated emission of wavelengths longer than that of the stimulation wavelength. The absorbed dose is obtained from the amount of the light emission. Imperfections ...
