ABPM 203M – Mobile Alpha Beta Particulate Monitor

Category: Characterization > Monitors > Radiation Monitors
Reference # : Model No :

The ABPM 203M™ Mobile Alpha Beta Particulate Monitor is a lightweight and portable instrument designed for real-time measurement of alpha and beta particulate radiation. Part of the RAMSYS™ product line, the ABPM 203M can be deployed directly in areas where workers are exposed to radioactive particles, particularly near the respiratory tract. It features an extendable sensor that allows close proximity measurement, ensuring accurate results in environments with high radon and thoron levels. The monitor uses a dual silicon detector for gamma compensation and incorporates static and dynamic compensation algorithms to mitigate interference from radon and thoron progenies. Additionally, it offers real-time alpha spectrometry and extended filter cassette autonomy, with up to 6 months of continuous operation with the moving or fixed filter card option.

Benefits

The ABPM 203M provides precise alpha and beta particulate measurement, particularly in environments with elevated radon levels, such as workplace areas with significant radiation exposure. Its dynamic and static compensation capabilities for radon and thoron progenies enhance accuracy by reducing the impact of background radiation. The real-time alpha spectrometry feature enables immediate assessment of particulate contamination, making it ideal for monitoring worker safety. The device is also designed for cost-effective operation, with a long filter cassette life of up to 6 months, minimizing maintenance and reducing operational costs. Its portability and lightweight design make it easy to transport and deploy directly in the field, while the use of continuous filter and online spectroscopy reduces the need for manual intervention.

Limitations

Despite its many benefits, the ABPM 203M may not be suitable for measuring very low-level radioactive particulates, as it is optimized for environments with high levels of radon and thoron. The extended filter cassette autonomy of up to 6 months may still require replacement or maintenance after long periods of operation, which could cause some downtime. While the monitor is designed for unattended operation, it may require periodic calibration or adjustments depending on the conditions of use. Additionally, the portability and extended sensor design may not be ideal for all environments, particularly where space or accessibility is restricted. The device’s reliance on a filter card system may also impose additional operational requirements for users to ensure accurate and continuous data collection.
