  • Predicting the radiation risk to European Space Agency astronauts

    European scientists have developed the most accurate method yet for predicting the doses of radiation that astronauts will receive aboard the orbiting European laboratory module, Columbus, attached to the ISS this week.  The new software package accurately simulates the physics of radiation particles passing through spacecraft walls and human bodies. Such techniques will be essential to use for ...

  • Astronauts face radiation threat on long Mars trip

    Astronauts traveling to and from Mars would be bombarded with as much radiation as they'd get from a full-body CT scan about once a week for a year, researchers reported Thursday. That dose would, in some cases, exceed NASA's standards and is enough to raise an astronaut's cancer risk by 3 percent. As plans for deep space exploration ramp up, radiation is a big concern — from high-energy ...

  • 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 ...

  • Administrator Lisa P. Jackson, testimony before the U.S. Senate committee on environment and public works and subcommittee on clean air and nuclear safety

    Good morning, Madam Chairman, Chairman Carper and Members of the Committee. I am pleased to be here today to discuss EPA’s role in monitoring for radiation associated with the Fukushima Daiichi nuclear power plant emergency in Japan and the possible implications for the United States. Let me begin by expressing my sympathy for those who have lost loved ones from the earthquake and tsunami ...

  • Are TGFs hazardous to air travelers?

    Instruments scanning outer space for cataclysmic explosions called gamma-ray bursts are detecting intense flashes of gamma-ray energy right here in the friendly skies of Earth. These terrestrial gamma-ray flashes, or TGFs, blast through thunderstorms close to the altitude where commercial airliners fly. In fact, they could be too close for comfort. In a recent study,* scientists estimated that ...

  • Worldwide nuclear accident monitoring network launched

    An IAEA-based international nuclear emergency response network has become operational through receipt of its first pledges of assistance from four Member States. Finland, Mexico, Sri Lanka and the United States have stepped forward to make the initial commitments to the Response Assistance Network (RANET), a global response arrangement designed to coordinate international assistance in case of a ...
