The fire at the La Hague silo led to air contamination during the fire. All air contamination measurements made during the event revealed only the release of cesium 137 with maximum concentrations of 48.1 GBq.m⁻³ of air. After detailed studies, total cesium 137 releases were estimated to be between 740 and 1,850 GBq. The fire also caused soil contamination with very low contamination areas. This contamination was found inside the site on about one hectare; it affected building 130 overlooking the silo and the surrounding areas. The maximum values recorded were 111.10³ Bq.m⁻² cesium 137 at the site, and contamination remained low off-site and did not exceed 3.7.10² Bq.m⁻² of cesium 137.
