Cesium-131 (Cs-131)

Cesium-131 (Cs-131) 
Half-Life: 9,7 (days)

The half-life of Cs-131 is 9,7 days. It decays by electron capture emitting photon radiation in the X-ray range (29.5 - 33.5 keV). The optimal combination of its half-life and radiation energy makes Cs-131 an attractive radioisotope for brachytherapy of malignant tumors. The list of organs include prostate gland, lungs, brain, mammary gland, etc. Implementation of Cs-131 in clinical practice is considered one of the most important innovations in brachytherapy for the past 20 years.
