Phytosanitary treatment using radiation is a current trend in the fruit export-import trade. Radiation dosimetry is a key factor in determining the success of phytosanitary treatment. This study will explain 3 key stages in determining the quality of radiation in phytosanitary treatment.

Based on dosimetry guidance standards, calibration must be traceable to a primary laboratory or national secondary laboratory. Calibration results are tested by comparing between labs. The results of the intercomparison can assess the trueness and reproducibility of the measurand to reference dose. Third, Simulation is used as a treatment planning system to ensure that the qualification and dose mapping process is carried out efficiently in terms of cost and accuracy of results.

Calibration was carried out on the Gamma Cell 220 irradiator at a certain dose range. To prove the trueness and reproducibility of the calibration, a laboratory comparison was carried out. The results of the intercomparison obtained: meansurand (Gy) of 102, 397, 1000, while the reference results (Gy) were 97, 381, 958. Then statistical tests were carried out using the Grubbs Test and Mandel h and K test methods. Where the results of the Grubbs Test and Mendel show the ability to have true value and good reproducibility. The final stage is creating a Monte Carlo-based simulation. The results were then tested using the t-test statistic to assess the difference between the simulation and the actual measurement of the absorbed dose value in the simulation. The t-test shown it is concluded that it failed to reject the null hypothesis, which means There is no significant difference. These three stages are techniques for phytosanitary processes to obtain radiation doses that are more precise, reproducible, and predictive.
