Argentinian authorities have declared an alert following the disappearance of a capsule containing cesium-137 from a medical laboratory in Rosario. The missing substance poses a health risk if direct contact occurs, though the radiological danger is considered low provided the capsule remains intact. A crisis protocol has been activated, and a search is underway to locate the radioactive material. Officials are working to determine how the capsule went missing and are assessing potential contamination risks. The incident has prompted a national response, with coordinated efforts to track and recover the source. Authorities emphasize the importance of public cooperation in the search and are providing guidance on safety measures.
