Radionucle Safety Guideline for Cl-36

Physical Data

• Radiation: Betas - 0.710 MeV (99.9%)

Range

• 2.6 m air unshielded

Half-life

• Physical: 3.08 x 10⁵years
• Biological: 10 days

External and Internal Hazard

• Cl-36 is a medium energy beta emitter that presents both an internal and external hazard.
• Uptakes of Cl-36 are assumed to be distributed uniformly among all organs and tissue of the body.

Shielding

• Total absorption of beta radiation is achieved with 2.4 mm perspex or 1.5 mm glass.

Safety Guidelines

• Film badges and dosimeter rings are required
• Segregate waste separately
• Whole body and ring dosimeters are required.
• Wear a lab coat and disposable gloves.
• Cl36 beta particles have sufficient energy to penetrate gloves and skin .
