Atomic nuclei consist of protons and neutrons bound together in tiny bundles at the center of atoms. Radioactive nuclei are nuclei that are unstable and that decay.
Neutrinos are produced through radioactive interactions, such as solar fusion, supernovae, radioactive decay, and when cosmic rays collide with the earth's atmosphere. It was enrico fermi who developed a more complete theory of neutrino interactions and who coined the term neutrino for these particles.

An effective radiation safety and alara program is only possible when a commitment to safety is made by all those who are involved in the use of radiation. This may include members of the radiation safety committee, radiation safety division staff, medical personnel, research faculty, and all radiation workers.
Risk assessment: the philosophy underlying radiation protection. Our present understanding of the role of ionizing radiation in the induction of malignant disease and genetic disorders has taken many years to develop. Over this period there has been a considerable degree of international collaboration in producing recommendations for good practice.
Radioactivity demonstrated that the atom was neither indivisible nor immutable. Instead of serving merely as an inert matrix for electrons, the atom could change form and emit an enormous amount of energy. Furthermore, radioactivity itself became an important tool for revealing the interior of the atom.

An important aspect of my philosophy is that one should work toward goals that might be difficult along the way but expected to provide the greatest pleasure when an individual looks back over her/his career.
Radio waves were first predicted by mathematical work done in 1867 by scottish mathematical physicist james clerk maxwell. His mathematical theory, now called maxwell's equations, predicted that a coupled electric and magnetic field could travel through space as an electromagnetic wave.
