Abstract
A method of determining the doses of neutrons, gamma and X-ray photons, beta, alpha and other ionizing radiations using a method of image processing in spatial and frequency domain that produces parameters that are related to the radiation dose absorbed in a luminescent material. Portions of the luminescent material may be covered by different converters to allow for doses of different radiations to be discriminated.

A method comprising the following steps:
- (a) providing a luminescent material providing one or more radiation-induced fluorescence signals;
- and
- (b) removing the one or more radiation-induced fluorescence signals from the luminescent material by illuminating this luminescent material with laser light at power density sufficient for multi-photon absorption and photo-ionization.
The method 50, wherein the luminescent material comprises aluminum oxide doped with carbon and magnesium and the optical illumination is performed with pulsed laser light with the wavelengths in the range between 300 and 350 nm.
