These are known as the uranium series, the actinium series and the thorium series, each named after the element at which the series start (except the actinium series which starts with a … Natural radioactivity the activities (like the use of fertilizers). Geoder. They are described as radioactive, and are known as radioisotopes or Nuclear Radiation Natural Radioactivity Nuclear Equations Producing Radioactive Isotopes … ATOMIC NUCLEUS AND RADIOACTIVITY E.H.ANNEX Medical Physicist Batra Hospital and Medical Research Centre New Delhi 62 2. This radiation comes from isotopes of carbon and potassium, as well as thorium and uranium, which may be found in soil, rocks, or water.The latter two isotopes decay into radon and radium, which are extremely radioactive, though rare.Their decay rate is also quite long — for example, … The level of natural background radiation varies depending on the location, and in some areas the level is significantly higher than average (sample S0 inside the factory).
