Download file to see previous pages Isotopes with the tendency to radioactivity refer to atoms with an unstable nucleus. The inner core, which consists of the nucleus, has unbalanced energy. The dense package of neutron and proton makes the nucleus unstable. The lack of stability is the basis for the decomposition process. Therefore, through decomposition, the nuclei transform its configuration and components to a less strength and steady condition. This decomposition obeys the exponential law, which states ‘the number of decomposition per second is always equivalent to the amount of the undecayed nuclei available.' The law is also applicable to the rate of decay (activity). The decay depends on the half-life of the nuclide. Half-life is the duration/time that a nucleus takes to be halved.Positrons refer to the subatomic molecules that are equal in mass to an electron with characteristic of carrying a positive charge. When the positron decay (β+), its nuclei changes one of the core protons (p) to a neutron (n), while emitting positron (β+) to attain a positively charged nature referred to as neutrino (ν).Upon the release from the initial nucleus, the high positron moves across a few millimeters through the tissue until it attains thermalization, during the acquisition of thermal energy, the positrons arrive at thermal energies. They begin connecting with electrons either through annihilation that produce two 511 keV photons to take anti-parallel positrons frame or through development of the hydrogen. ...Download file to see next pagesRead More

Positron Annihilation
When a low energy positron collides with a low energy electron, there is an emittance of two gamma rays in the opposite direction. This phenomenon, also called positron annihilation, results in two gamma rays at 180° and with 0.511 MeV of energy moving in opposite directions.

Implementation of the Final Solution
When it comes to explaining the Final Solution, Nazi anti-Jewish policy, logic becomes an even smaller share in the analysis. According to Norman Rich, German racial programs were carried out with "almost total disregard for political, military or economic consequences." Such policies "cannot be dismissed" as mere political opportunism, but "onlyas the policies of a fanatic ideologue."1 Some analysts go even further, seeing Nazi anti-Jewish policy not only as an irrational 'slideshow' of military expansion, but as its very basis:
