Article Synopsis
- - Aerosol monitoring for radioactivity is well-established but can be improved by enhancing equipment specifications to allow for more samples per day without compromising detection sensitivity.
- - The study models potential radioactive releases of elements like Ba and I, ranging from small to large quantities over a year to account for natural variations in how these particles spread in the atmosphere.
- - Advancements in sampling equipment could lead to better detection rates across more monitoring stations, increasing resilience to outages and improving the ability to locate sources of low-yield radioactive releases, especially with the implementation of dual-detector technology.
Pacific Northwest National Laboratory (PNNL) staff developed the Radionuclide Aerosol Sampler Analyzer (RASA) for worldwide aerosol monitoring in the 1990s. Recently, researchers at PNNL and Creare, LLC, have investigated possibilities for how RASA could be improved, based on lessons learned from more than 15 years of continuous operation, including during the Fukushima Daiichi Nuclear Power Plant disaster. Key themes addressed in upgrade possibilities include having a modular approach to additional radionuclide measurements, optimizing the sampling/analyzing times to improve detection location capabilities, and reducing power consumption by using electrostatic collection versus classic filtration collection.
