Radiation can be either ionizingor non-ionizing, depending on how it affects matter. Non-ionizing radiation includes visible light, heat, radar, microwaves, and radio waves. This type of radiation deposits energy in the materials through which it passes, but it does not have sufficient energy to break … Meer weergeven As previously indicated, matter gives off energy (radiation) in two basic physical forms. One form of radiation is pure energy with no weight. This form of radiation — known as electromagnetic radiation — is … Meer weergeven As previously indicated, large unstable atoms become more stable by emitting radiation to get rid of excess atomic energy (radioactivity). This radiation can be emitted in the form of positively charged alpha … Meer weergeven Alpha particlesare charged particles, which are emitted from naturally occurring materials (such as uranium, thorium, and radium) and … Meer weergeven In some elements, the nucleus can split as a result of absorbing an additional neutron, through a process called nuclear fission.
