There is a need for dosimetric calibration procedures in industrial irradiation plants, specifically for self-shielded irradiation systems. Objective: To implement high dose dosimetry in the routine control of irradiated materials within a self- shielded irradiator. Methods: We worked with 32 dosimeters; we divided the dose range used into 8 points and used four RED Perspex dosimeters per point. We measured the specific absorbance for each dosimeter; plotted these values against dose and produced a third- degree polynomial fit as a calibration curve. Results: We obtained the calibration curve with an r2 of 0,9997. The uncertainties due to the dispersion of the dosimeters and the calibration curve were 1,39% and 0,22%, respectively, for a total uncertainty of 4,80%. This uncertainty includes dose determination with a factor coverage (k) equal to 2 for a 95% confidence interval. Conclusion: Perspex RED dosimeters can be used for routine control of irradiated products in a self-shielded irradiator system.]]></p></abstract>

Métodos: Trabajamos con 32 dosímetros; dividimos el rango de dosis en 8 puntos y utilizamos cuatro dosímetros RED Perspex por punto. Medimos la absorbancia específica de cada dosímetro; trazamos estos valores contra la dosis y produjimos un ajuste polinómico de tercer grado como curva de calibración. Resultados: Obtuvimos la curva de calibración con un r2 de 0,9997. Las incertidumbres debidas a la dispersión de los dosímetros y a la curva de calibración fueron del 1,39% y 0,22%, respectivamente, para una incertidumbre total de 4,80%. Esta incertidumbre incluye la determinación de la dosis, con un factor de cobertura (k) igual a 2 para un intervalo de confianza del 95%. Conclusión: Los dosímetros de Perspex RED sirven para el control rutinario de productos irradiados en un sistema de irradiador auto blindado.]]></p></abstract>
