Radiation therapy uses ionizing radiation to treat cancer i.e. to destroy cancerous cells. There are two techniques in radiation therapy that are used to treat cancer…

Ionizing radiation can kill or change the nature of living cells. The effects of the damage inflicted by the ionizing radiation may be severe and cause immediate…

Main objective of this lecture is to present on Effects of Radiation on Living Things. Radiation may be absorbed by the medium it passes through. Radiation can kill…

Nuclear fission is a nuclear reaction in which a heavy nucleus splits into lighter nuclei and energy is released. Nuclear fusion is a nuclear reaction…

Major objective of this lecture is to present on Mass Energy Calculations. The change of energy is related to the change in mass, according to the mass-energy…

The aim of this lecture is to present on Applications of Radioactive Isotopes. A radioactive tracer is a very small amount of radioactive isotope added to a…

The rate of radioactive decay, that is the number of disintegrations per unit time, is proportional to the number of radioactive nuclei in the sample. The…

Prime objective of this lecture is to present on Nuclear Bombardment Reactions. In 1919, Ernest Rutherford discovered that it is possible to change the nucleus of one…

Basic objective of this lecture is to present on Types of Radioactive Decay. There are three major types of nuclear decay that radioactive particles can undergo: alpha,…

General objective of this lecture is to present on Nuclear Stability. Nuclear Stability is a concept that helps to identify the stability of an isotope. The existence…
