CHLORINE-36 (Cl-36)
Chlorine-36 is a medium-energy beta emitter. Use a thin-end window G-M detector or liquid scintillation
counter for detection.
1.
Maximum energy: 0.710 MeV (the average energy is 0.233 MeV).
Maximum range in air: 7 feet (2 m).
2.
Maximum range in tissue: 0.1 inch (2.6 mm).
3.
IAEA toxicity classification: High-medium.
4.
Physical half-life: 3 x 105 years.
5.
Effective half-life (Teff): 10-29 days.
6.
7.
Critical organ:
o
Whole body for transportable compounds.
o
Lung for inhalation.
o
Lower large intestine for ingestion.
8.
Personnel monitoring: Urinanalysis, finger rings.
ALI:
9.
0.2 mCi (7 x 106 Bq) by inhalation.
o
2 mCi (7 x 107 Bq) by ingestion.
o
Shielding: 0.25 inches (6mm) of plexiglass.
10.
11.
Special Considerations:
o
Cl-36 beta particles have sufficient energy to penetrate gloves and skin.
o
When handling millicurie quantities, do not work over an open container.
o
Avoid glove and skin contamination or ensure that it is promptly detected and removed.
