The primary health concern associated with Cesium-137 is an elevated risk of cancer due to DNA damage from long-term, repeated low-dose exposure.

Radioactive shrimp. That’s not a typo. That’s not clickbait. That’s what’s going down at Walmart right now. The retail giant has issued a multi-state recall for several lots of its Great Value frozen shrimp after the FDA flagged potential contamination with Cesium-137 — a radioactive byproduct most commonly associated with nuclear reactors and atomic bombs.

The FDA is warning consumers not to eat certain frozen shrimp products sold at Walmart after other products from the same company tested positive for a radioactive substance.
