SIMPLE RADIATION TRANSFER FOR SPHERICAL STARS
... We obtained only one half of the radiation energy density expected under LTE conditions for the temperature T , because radiation was coming from one hemisphere only. The radiative energy flux may be calculated for our case: ...

... Radioactivity ■ In the late 1890’s Scientists noticed some substances spontaneously emitted radiation in a process called radioactivity. This is because their nuclei is unstable ■ Rays and particles emitted are called radiation ■ Radioactive atoms undergo changes that alters their identity and allo ...

... the centre of the atom is a very small region called a nucleus. The nucleus houses protons and neutrons. The electrons form a cloud around the nucleus. The neutrons hold mass containing particles (protons) together in the nucleus. When an atom has too much energy, it dissipates energy through emissi ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
