Cesium is an incredibly toxic element that has been unleashed into our environment from nuclear testing and nuclear accidents like the Fukushima nuclear disaster in Japan in 2011.
Sadly, the reactors are still releasing large amounts of radioactive cesium into our environment and reports say that it will contaminate all the world’s oceans in time.
Cesium can be a big causative factor in fatigue because it displaces potassium in the body (1). This interferes in numerous processes that affect energy production, namely suppression of enzymes involved in the energy exchange of cells. (2)
Naturally occurring, it exists in the environment in a non-radioactive, stable form. We are not concerned with this nontoxic form of cesium. Radioactive, unstable cesium is created during the process of nuclear fission (used in nuclear power plants) and is incredibly dangerous to human health (3).
The two radioactive cesium isotopes most notable for their damaging effects on human health are cesium-134 and cesium-137 (3). Cesium-137 is the most dangerous substance released in nuclear disasters like Fukushima or Chernobyl (4).
