Electronic Personal Radiation Dosimeters Enable Best Practice Procedures
ADM stocks the latest generation of Thermo Scientific EPDs (Electronic Personal Radiation Dosimeters).
The Thermo Scientific Trudose electronic personal radiation dosimeters will be the first to offer Bluetooth connectivity. This promises the benefit of being able to send radiation dose measurements continuously to a computer for real time monitoring of staff exposure without having to inspect each EPD individually.
The Thermo Scientific Truedose EPDs could further enhance radiation workers safety and their ability to minimise their exposure.
Comprehensive radiological protection programs are essential for any organisation, whose employees and contractors work with radiation, or have the potential to be exposed to radiological sources.
Whether these sources are industrial or medical, careful planning and implementation of procedures is required to not only minimise exposure, but to also measure the extent of any radiation exposure.
Many organisations rely on passive radiation dosimetry techniques.
Radiation dosimeters such as TLD or OSL are 'passive' as they do not provide direct readouts and can operate without any active means. The measured dose is usually taken as an estimate for the effective dose, which is recorded and reported after evaluation. Typically passive dosimeters provide monthly or quarterly accumulated dose.
In the vast majority of cases these passive techniques work perfectly well. However, they do have several drawbacks.
They don’t provide any feedback to the wearer as to how a certain activity is impacting their received dose and they are also ineffective for visitors to a site due to the administrative challenges in issuing them for a short duration.
Active Radiation Dosimeters, such as the Thermo Scientific EPD TruDose Electronic Personal Dosimeter overcome this problem by providing a direct display of the accumulated radiation dose and dose rate to the wearer. They also have some additional functions such as alarm threshold settings for dose or dose rate values. As well as audible and visual indication of the dose rate level.
The Thermo EPD TruDose has internal data storage so minute by minute radiation dose rates can be recorded and downloaded later. They also operate over a wide energy range from 15 keV through to 10 MeV, capturing radiation of all energies. This is important when accurately measuring radiation from a wide variety radiation sources which may also include X-Rays.
The EPD TruDose has integrateed Bluetooth capability. This takes active radiation dosimetry monitoring to a new level, providing unparalleled real-time dose reading, improving the safety of staff and students.
You will be able to continually monitor a large number of staff and students in real time, which is something a passive system cannot do.
The Bluetooth functionality of the Thermo Scientific EPD TruDose enables you to use telemetry to network the dosimeters, so that real time readings can be taken remotely. You will be alerted to any alarm situations immediately, allowing you to take immediate intervention to reduce a wearers radiation exposure.
Some organisations will issue a Thermo Fisher Scientific EPD to any visitor to site in order to accurately measure their radiation exposure.
We also have customers who have implemented an area monitoring solution using EPDs mounted at strategic locations around a site. The ability to quickly and easily interrogate the TruDose's internal memory with a laptop PC and IR reader actually makes this an effective area monitoring solution as the EPDs can be easily moved from one location to another with minimal fuss. This demonstrates how an electronic personal radiation dosimeter can be used to enable best practice procedures to minimise employee and visitor radiation exposure.
