Dosimeter

A method of using dosimeter comprising a measurement chamber and a light sensor, wherein the measurement chamber is filled with a fluorophore and is lightproof, and wherein the light sensor is configured to detect fluorescent light generated by ionizing radiation in the fluorophore in the measurement chamber and to generate a signal that is proportional to the fluence of the detected fluorescent light, the method,

• comprising:
• using the dosimeter for measuring a radiation dose of a pulsed ionizing radiation having radiation pulses having a length of less than 10 ns, wherein the ionizing radiation has an energy of more than 8 keV.
