Radiation for dummies

Meet Helga and Zohar, the dummies destined for a pioneering lunar flyby to help protect space travelers from cosmic rays and energetic solar storms.

Photonic radiation sensors survive huge doses undamaged

Researchers at the National Institute of Standards and Technology (NIST) have published landmark test results that suggest a promising class of sensors can be used in high-radiation environments and to advance important medical, ...

New measurements to guide radiation therapy

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. Ionizing radiation used for cancer treatment includes ...

Lightning produces afterglow of gamma radiation

Lightning can produce X-rays and gamma radiation. In the past, researchers thought that this phenomenon only lasted for a very short time, about one ten-thousandth of a second. However, the ionizing radiation of lightning ...
