Consumer Products

Any household product that contains a quantity of radioactive material yielding Ionising Radiation for reasons of functionality of that item. Examples include ionisation smoke detectors (e.g. Am-241) and luminising items such as watches and clocks which may contain, for example, radium. Consumer products from by-gone-days are a potentially significant radiation hazard if not carefully stored and protected from damage.
