Plant Validation


The purpose of plant validation is to study the dose inside the product box, to identify the maximum and minimum dose locations and also to know the dose in each shelf of the carrier. This helps in finding the speed at which conveyor is to run to get the desired dose at a particular source activity. Speed of the conveyor is the only parameter which effects Gamma Radiation.

AVPPL’Gamma Irradiation Facility is fully validated. Plant Validation is done after each major change in system. Usually in any Gamma Radiation Facility, Source loading is the major change which occurs frequently due to decay of source and depending on business, source is augmented every 1-2 years. Plant validation is done using dummy material say saw dust/rice husk. After the plant validation results are found acceptable, the plant is re-started for routine commercial operation.
