Cesium Ion Overview

The cesium ion (Cs⁺) is the monovalent cation of cesium. It is not a typical therapeutic target but can be relevant in toxicology, particularly in cases of radiation exposure involving radioactive cesium isotopes. Cs⁺ can interfere with normal biological processes, especially those involving potassium ions (K⁺), due to its similar charge and ionic radius, though larger size. Prussian blue is used as a chelating agent to remove cesium from the body.

Mechanism of Action

Prussian blue binds to cesium ions in the gastrointestinal tract, preventing their absorption and promoting their excretion in feces.

Biological Functions

Ion transport disruption
Potassium channel interference
Enzyme Inhibition (at high concentrations)

Safety Considerations

  • Cardiotoxicity (at high concentrations)
  • Neurological effects (at high concentrations)
  • Potential disruption of potassium-dependent processes
