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…

Main purpose of this lecture is to present on Vertical Structure of Ozone Cycle. The ozone–oxygen cycle is the process by which ozone is continually regenerated in…

Principle purpose of this lecture is to present on Simulation at NASA for the Space Radiation Effort. Here briefly focus on Simulation at NASA for Space Radiation. The…

A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. For example, the nuclide symbol for uranium-238. The total charge is conserved during…

This lecture introduce on Nuclear Chemistry. In this lecture we will look at two types of nuclear reactions. Radioactive decay is the process in which a nucleus…

Major objective of this lecture is to present on Ultraviolet Radiation. Ultraviolet Radiation(UV) is simply one form of energy coming from the sun. Even though you may…

Space radiation is composed of energetic charged particles (atoms with all of the electrons striped). Astronauts are exposed to secondary neutrons as well. The radiation environment of…
