Atoms which have unstable nuclei are radioactive and are called radioisotopes or radionuclides. The change that an unstable nucleus undergoes is called disintegration or decay. When unstable nuclei ...

An Israeli company named Alpha Tau Medical is breaking new ground in the destruction of cancerous tumors. Alpha Tau medical ...

Alpha particles come from the nucleus of a radioactive atom. They consist of 2 protons and 2 neutrons; hence have a 2+ charge. A few centimeters of air will stop them. Alpha radiation consists of ...

However, apparently inhaling or ingesting radioactive glass dust can be a problem. Alpha particles can’t go very far through your skin. But once inside your body, they can be hazardous.

Physicists develop innovative technique using carbon-dioxide lasers to detect radioactive materials from safe distances for ...

JON CHASE:'Gamma radiation is pure energy, 'but alpha and beta radiation exist in forms of subatomic particles. 'In this case we are looking at the effect of alpha particles. JON CHASE:'The ...

The researchers used a carbon-dioxide laser emitting long wave infrared radiation at a wavelength of 9.2 micrometres to accelerate the electrons, and were able to detect alpha particles from a ...
