Abstract:
1. A method of radiation processing of a product package o of essentially equal rectangular size in a device having a radiation source, a collimator having a variable aperture, and a turntable, said radiation processing resulting in a point in the product package where the dose is minimal (D min point) and a point in said product package where the dose is maximal (D max point) comprising the stops of: determining a first value of the collimator aperture, by increasing said aperture from a small value, where the D determining a second value of the collimator aperture, by further increasing the collimator aperture up to a point where the D processing said package with radiation, the collimator aperture being kept at a constant value comprised between said first and said second value, the turntable being rotated at a variable speed.
