INT-NIOSH Study Evaluates Risks for Pregnant Flight Attendants
Flight attendants often travel across time zones, working when others normally sleep, and are exposed to cosmic radiation from the sun and space. A NIOSH study published earlier this year examined the risks of cosmic radiation, circadian disruption (from working during normal sleep hours), and other work exposures on pregnancy outcomes for flight attendants and studied 958 pregnancies among 764 ...

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 ...

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 ...

NORM waste - a safe, yet more sustainable & economical approach
For typical NORM material, exceeding the acceptable yearly radiation dose is what is concerning, rather than any immediate health effects. Surpassing the yearly radiation threshold leads to a higher risk of developing cancer and other life-threatening diseases. A second term, called TENORM is also used quite often: Technologically Enhanced Naturally Occurring Radioactive Materials. TENORM occurs ...

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 ...

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 ...
