DOE-HDBK-1106-97
CALCIUM-45 (Ca-45)
Calcium-45 is a low-energy beta emitter and may be detected with a thin-window probe.
Calcium-45 is commonly used with animal studies.
1. Maximum beta energies: 0.257 MeV (the average energy is 0.086 MeV).
2. Maximum range in air: 20 inches (52 cm).
3. Maximum range in tissue: 0.62mm.
4. IAEA toxicity classification: High.
5. Physical half-life: 163 days.
6. Effective half-life (Teff): 163 days.
7. Critical organ: Bone.
8. Personnel monitoring: Bioassay, initially by urine, later by feces. NOT detected with a
dosimeter (thermoluminescent dosimeter or film).
9. ALI:
0.8 mCi (3 x 107 Bq) by inhalation.
2 mCi (7 x 107 Bq) by ingestion.
10. Shielding: 3mm of plexiglass.
11. Special Considerations:
Detection of Ca-45 by radiation survey instruments requires special care due to the low
efficiency of detection.
