☢️ Research shows crushed concrete from nuclear sites can effectively trap radioactive strontium-90 for the long term, especially when exposed to air or treated with phosphate.

💨 In air-exposed conditions, concrete removed about 82% of strontium within three months by forming calcite, a mineral that locks strontium into its structure.

💧 Phosphate treatments boosted strontium removal even in air-limited environments, with up to 98% captured in air-exposed phosphate systems within 48 hours.

🌍 These findings could help improve strategies for managing radioactively contaminated land and inform on-site disposal decisions.
