Section 2
SECTION 2: Hazards identification
Radiological Hazard Warning THIS MATERIAL SHOULD ONLY BE USED BY PERSONS QUALIFIED TO HANDLE RADIOACTIVE MATERIAL! SRM 4233E is a radioactive material, cesium-137, with a massic activity of approximately 298 kBq•g-1 in hydrochloric acid. Cesium-137 decays by beta-particle emission to barium-137m, which decays by internal conversion. During the decay process X-rays and gamma rays with energies from approximately 3 keV to 662 keV are emitted.
