About the DoseControl Dosimetry System
The DoseControl® is an off-the-shelf dosimetry system used for generating dosimetry reports for any commercial/industrial radiation processing application, with a dose range of approximately 100 Gy to 300 kGy (depending on dosimeter type).
The DoseControl® dosimetry system integrates a powerful FDA 21CFR Part 11/EU Annex 11 conforming dosimetry software with a Thermo Scientific spectrophotometer, controlling the measurement process and making it simple to create and maintain dosimetry records. This system is a versatile solution for industrial routine dosimetry applications, and complies with all industry standards for the radiation sterilization industry.
DoseControl is designed for many types of dosimeters
DoseControl has specialized dosimeter holders for B3 radiochromic, FWT radiochromic, GAFCHROMIC HD-V2 film, CTA film, and Harwell PMMA (Red and Amber Perspex) dosimeters.
B3 dosimeter IDs can be scanned using an internal barcode scanner, designed to integrate with DoseControl
Harwell PMMA dosimeter thickness can be measured using an internal laser micrometer, designed to integrate with DoseControl.
DoseControl integrates with hardware components to control the dosimeter measurement process
Spectrophotometers
DoseControl software connects to and controls one of the following spectrophotometers:
Thermo Scientific Genesys 20 spectrophotometer*
The Thermo Evolution Spectrophotometer (Evo) and the Thermo GENESYS 30 (G30) are the instruments that provides complete compliance with all of the stated requirements in FDA 21CFR part 11/EU Annex 11. A barcode scanner can be mounted inside the sample compartment to capture the B3 dosimeter ID serial number for each measurement (see Barcode Scanners below).
The Genesys 20 (G20) spectrophotometer does not provide the internal barcode scanning feature for B3 dosimeters. The Genesys 20 also lacks the ability to return its serial number by command, and is not compliant with FDA 21CFR part 11 traceability requirements.
IMPORTANT - GEX DoseControl software can integrate with the Genesys 20. Thermo Genesys 20 instrument retirement date is June 30, 2023. Thermo is not supporting the Genesys 20 spectrophotometer after the retirement date.
GEX dosimeter holders
GEX dosimeter holders allow the user to insert a dosimeter into a spectrophotometer in a reproducible manner so that the optical dosimeter is perpendicular to the light source of the spectrophotometer to ensure accurate measurement.
GEX manufactures specialized baseplates and holders that fit inside the sample compartment of the the Thermo Evolution, the Thermo GENESYS 30, and Thermo G20 spectrophotometers.
Barcode scanners
Internal and external barcode scanners are options for any spectrophotometer as an automatic way to enter dosimeter IDs into the software.
The Evolution and GENESYS30 spectrophotometer can be fitted with an internal barcode scanner to capture the B3 dosimeter ID serial number for each measurement, permanently linking each dosimeter ID to its dose measurement.
Laser Micrometer
An integrated laser micrometer is an option for the measurement of PMMA dosimeters. The laser micometer is mounted inside the Evolution spectrophotometer sample compartment and captures the dosimeter thickness value at the same time as the absorbance measurement, ensuring traceability of the measurement to a given dosimeter so that one cannot accidently mix the absorbance and thickness measurements. Custom Gage Blocks are manufactured and certified for the calibration verification process of the laser micrometer.
Thermo Scientific Performance Verification Accessories
The Thermo Mercury Lamp is used for instrument re-calibration and performance verification testing.
The Thermo Spectronic Standards Set is the performance verification accessory used for the Genesys 20, GENESYS 30 and Evolution spectrophotometers
