For decades, scientists have known that ordinary matter — everything made of atoms — accounts for just 15% of the universe’s ...

CT-associated cancer could eventually account for 5% of all new cancer diagnoses each year, the study projects.

The level of background radiation in the air increased, and this had an effect on the production of steel, so that steel produced since 1945 has had elevated levels of radioactivity. This can be a ...

Basic approaches to radiation protection are consistent all over the world. The ICRP recommends that any exposure above the natural background radiation should be kept as low as reasonably achievable, ...

New research reveals CT scans may cause 103,000 cancer cases annually—equal to the cancer risk from alcohol and obesity.

NNSA’s Nuclear Emergency Support Team Aerial Measuring System aircraft will measure expected background radiation as part of standard preparations to protect public health and safety during the ...

The effective dose we receive from natural background radiation during one day is about 10 μSv. For a typical DXA examination, using technology that has become available over the last decade, the ...

This Cosmic Microwave Background Radiation (CMBR) is the conclusive evidence for the Big Bang theory. The 'temperature' of deep space has been measured as around 3K, not absolute zero, due to the ...
