A2. A person may possess, transfer and use any number of radium luminous devices without a licence, provided that radium is the only nuclear substance in the device and the device is intact and not tampered with.
Q8. What about public displays? A8. If a radium luminous device is on display, a public access boundary should be placed to exclude access to at least one metre from the display. Radium luminous devices should never be used in ‘hands-on’ displays.
