In English, there are no inflectional prefixes. Prefixes, like all other affixes, are bound morphemes. The word prefix is itself made up of the stem fix (meaning attach, in this case), and the prefix pre- (meaning before), both of which are derived from Latin roots. prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un-is added to the word happy, it creates the word unhappy.
the gamma radioactive decay is the least dangerous. Alpha, beta and gamma are the three main types of radioactive decay. yes, it is because of the spontaneous disintegration of the radionuclide in which it is emitting a large amount of radiation that will affect the DNA cells in the human body.
Arafat's body exhumed, tested. Polonium-210 is not a radioactive substance that emits gamma particles, which can travel through walls at extremely high energies. Instead, as polonium-210 decays, it releases alpha particles, which can't even pass through a piece of paper. But alpha particles are still dangerous. They travel short distances and retain a high amount of energy.
