Abstract
The present disclosure discloses a method for measuring and checking the irradiation of a product by a radiation source using a measuring device. After conveying the product in front of the radiation source, the radiation beam irradiates the front of the product and passes through to hit the at least two detectors, which are pointing to the same target zone of the radiation source by a collimator. Finally, the recorded signal of each detector is compared with the signals determined in the performance qualification.
Claims16
A method for checking the radiation dose received by a product by a radiation source comprising the following steps;
- measuring at least a reference signal Sdn,PQ(t) of the radiation dose by at least one detector of a series of at least two detectors during a performance qualification step received by a reference product, said series of at least two detectors comprising each a detecting part and a collimator placed at a predetermined distance from the radiation source in such a way that the said at least two detectors are arranged in a plane facing a converter generating the irradiation beam and pointing to a same target zone of the radiation source that is interrupted partially or fully by at least a portion of the product,
- conveying the product in front of the radiation source so that at least a portion of a front surface of the product is irradiated with an irradiation beam produced from said radiation source,
- measuring a signal Sdn,Process(t) of the radiation dose received by said product by each detector of the series of the least two detectors, and
- comparing each measured signal of the at least two detectors of the same series with the at least reference signal measured by the at least one detector by a controller.
