 Essay regarding Radiation Safety

Composition of the Atom

Dense nucleus composed of neutrons (0 charge) and protons (+ charge) and surrounded by orbital bad particals (- charge). Neutrons and protons firmly held in the nucleus although electrons are extremely loosely placed and are easy to remove. When ever electrons will be removed from the atom, two charged debris (ions) happen to be produced the positively incurred atom as well as the negative electron. Energy is absorbed to get rid of the electron from the atom.

Atomic Notation

Chemical signs such as C for carbon dioxide, H to get hydrogen, and Cs intended for cesium are accustomed to identify each kind of atom. The atomic number of the element is definitely designated while Z plus the mass amount is specified as A. The atomic amount is always equal to the number of protons in the atom. The mass number is usually equal to the sum from the number of protons and volume of neutrons. The mass number (A) is actually written like a superscript, as with 14C (carbon-14) or since C-14. The atomic amount is created as a subscript when used as in 6C (carbon- 14). However , since the chemical symbol identifies the element it truly is redundant to include the atomic number, it is therefore rarely utilized. Carbon-14, consequently , would be written as 14C or C-l4.

Unit of Radiation Energy

The electron volt (eV) is an extremely tiny unit which is equal to just one. 6 Times 10-12 ergs. It is only employed in radiation basic safety to express radiation energy. The electron watt is such a little unit it is usually drafted as mega- or kilo- electron volts which is a million electron v (MeV) or a thousand electron volts (keV), respectively.

Radioactivity

The atoms of all components will exist in two categories with respect to their balance. Some atoms have excessive mass-energy inside the nucleus and exist within an unstable kind. The unstable atoms happen to be moved toward attaining steadiness much such as an unstable car on top of a hill progresses to the underlying part to become even more stable. The process of going coming from an unstable to a more stable form may be the process that is called radioactive...
