Dosimetrics – Improved Measurement of Radiation Exposure
In this project we combined two devices for measuring radiation exposure into one. So called dosimeters are often worn by workers in the medical industry or within special industrial processes. Our client wanted to improve these important machines since they relied on two costly devices to read and erase the information on a monthly basis.
Our Final Result
Overview
Challenge
Usually, there is one device for reading the dosimeter and second device for erasing it. Due to budgetary reasons, there is a demand for a device combining reading and erasing functionality. But, vitally, the device should have the same frame size as a single module so as not to interfere with the wearer’s work.
Solution
The device is able to handle different types of dosimeters, identifying them via barcode or RFID. It detects the level of radiation exposure with a photomultiplier. The device is operated with customized embedded software.
Technologies
- FPGA
- CAD
- PCB Design
- Photomultiplier
Impact
Our newly developed device is able to both read and erase dosimeters in one process step. This reduces investment costs and also process times for enhanced efficiency. Furthermore, the weight and part costs were reduced because there was now a single device, instead of two.
