They thus produce heat in a solution, but don't produce ions. The electrons don't make beta particles, but stick to one part of the broken molecule thus one part has a plus charge and one a minus charge. E. Visible light waves are just strong enough to change very delicate molecules like rhodopsin, but not enough to change very many molecules. The eye uses this molecular change to detect the light. Another type of radiation is a piece of the nucleus that comes flying out when a radioactive isotope decays.
Beta rays are electrons that come from the nucleus a.
These can have various energies. Alpha rays on the inside of the body are more damaging as they leave a trail of damaged molecules that is concentrated 3. The half-life of an isotope is also important in toxicity. An isotope of a half-life of 1 minute will decay so rapidly, that it will not be dangerous after a short time. An isotope with a long half-life decays so slowly that not much radiation occurs over a short time period.
