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.
The reading on the detector increases when above a leak as the radiation can escape through the hole in the pipe more easily and also there will be an accumulation of the radioactive fluid in the ground around the leak. Radioisotopes used to find leaks are ones that emit gamma radiation with a short half-life.Gamma rays can easily penetrate pipes (even if they are underground) and reach the detector. Both alpha and beta particles would not pass through pipes, so could not be used.lthough ionising radiation can cause cancer, high doses of gamma (or X-ray) radiation can target and kill cancerous cells. This is called radiotherapy. About 40% of people with cancer undergo radiotherapy as part of their treatment.
