=== Snow White ===
Since 2018, SCK CEN has commissioned a ''Snow White'' (JL-900) ''Early Warning System''. This installation aspirates 900 m<sup>3</sup> of air per hour<ref>{{Cite journal |last=Frankemölle |first=J.

These filters are replaced and analysed on a weekly basis. Because the system sucks up large quantities of air, SCK CEN can detect very low concentrations of radioactivity in the airborne dust. In this way, radioactive emissions, even when originating from abroad, do not remain unnoticed. Detection of low concentrations may indicate an abnormal emission, such as a hidden leak, or signal a nuclear incident. Snow White successfully detected airborne [[Cs-137]] released during forest fires in the [[Chornobyl Exclusion Zone]] in [[Ukraine]] in 2020.<ref>{{Cite journal |last=De Meutter |first=Pieter |last2=Gueibe |first2=Christophe |last3=Tomas |first3=Jasper |last4=Outer |first4=Peter den |last5=Apituley |first5=Arnoud |last6=Bruggeman |first6=Michel |last7=Camps |first7=Johan |last8=Delcloo |first8=Andy |last9=Knetsch |first9=Gert-Jan |last10=Roobol |first10=Lars |last11=Verheyen |first11=Leen |date=2021-10-01 |title=The assessment of the April 2020 chernobyl wildfires and their impact on Cs-137 levels in Belgium and The Netherlands |url=https://www.sciencedirect.com/science/article/pii/S0265931X21001600 |journal=Journal of Environmental Radioactivity |volume=237 |pages=106688 |doi=10.1016/j.jenvrad.2021.106688 |issn=0265-931X|hdl=1854/LU-8746469 |hdl-access=free }}</ref>
