10.4: Radioactive Decay - Physics LibreTexts

WebRadioactivity is the term used to describe disintegration of atoms. The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation. WebRadioisotope calibrators are based on ionisation chambers. The principle of such an ionisation chamber is that the radiation to be measured passes through a gas (air, nitrogen or argon) forming ions as it does so. These ions are separated in an electric field with the electrons drifting towards the anode and the positive ions drifting towards ...
