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.

It is a form of ionizing radiation .
Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment.he radioactivity of all nuclear waste diminishes with time. All radionuclides contained in the waste have a half-life âthe time it takes for half of the atoms to decay into another nuclide âand eventually all radioactive waste decays into non-radioactive elements (i.e., stable nuclides).
