beta-emitting radioisotopes such as C14, H3, P32, P33 and S35; beta/gamma emitters such as Na22, K40, Ca45, I125;
Gas Chromatographs; x-ray machines; portable nuclear gauges, etc.
Note: ‘Radioactive waste’ is a separate matter, which refers to unwanted by-products of nuclear reactions such as at power-generating plants.
Definition of radioactive material:
Any substance, which consists of or contains any radioactive nuclide whether natural or artificial and whose specific activity exceeds 74Bq/g (0.002µCi/g) of chemical elements and which has a total activity greater than 3.7kBq (0.1µCi).
