Positively charged particles and free electrons are left behind after the collisions. Devices that are used to detect radioactivity are based on the ionizing ability of radiation. One such device is ...

The nuclear tests were testing safety measures, but resulted in something explicitly unsafe.

When it comes to reasons to not go out in the rain, lightning is more of a threat, but thunderstorms can increase background ...

A reluctant celebrity who coined the term “radioactivity”, she transformed the perception of women in science.

Further investigations have shown that the induced radioactivity of nickel is composed of two parts, cne decaying with a period of about 20 minutes and another with a period of the order of a few ...

All types of radiation become less intense as they travel further away from the radioactive material. This is because the particles or rays become more spread out. The thicker the substance, the ...

One type of smoke detector uses Americium-241, an alpha particle source, to detect smoke. The alpha particles pass between the two charged metal plates, causing air particles to ionise (split into ...

Radiation Basics Made Simple is a training module that introduces participants to the fundamentals of radiation and ...

A recent study suggests that without certain unmelted asteroids, Earth may not have had enough critical compounds for life to ...
