The nuclei of the atoms in some elements are unstable and emit radiation. The radiation can be of three types - alpha radiation, beta radiation and gamma radiation.

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 first module provides a basic understanding about radiation - what it is, where it comes from and the different types of radiation amd how people can protect themselves from its adverse effects.

The experiments we have made have confirmed this anticipation, and shown that in every case in which light is scattered by the molecules in dust-free liquids or gases, the diffuse radiation of the ...

both in the Lab's Chemistry Division. Wishart and his collaborators used these facilities to measure the rates and ...

Their findings are published in the journal Physical Chemistry Chemical ... of reactions of the two types of chromium ions with reactive species generated by radiation in molten salt.
