Phosphorus-32
P-32 |
Half Life: 14.29 days
Radiation: beta
Max. Energy: 1.71 Mev (100%) |
Range in Air: 6 meters
Range in Water: 8 mm
ALI: 400 mCi
DAC: 2E-7 uCi/mL |
Hazard: The beta radiation from mCi quantities represents an external radiation hazard. Large quantities of material (100 mCi) can produce significant amounts of secondary radiation, Bremstrallung Radiation. Ingestion and inhalation are possible routes for an internal exposure.
| Dose rate for 1 mCi of P-32 over 1 cm-sq of skin |
For 1 mCi P-32 in 1 ml of water |
| At 10 cm: 22 rads/hr |
At surface: 780 rads/hr |
| At 1 cm: 200 rads/hr |
|
| At surface of skin: 2,000 rads/hr |

Safety Precautions:
- Follow General Precautions for working with radioactive material.
- Wear whole body and ring badge when using mCi quantities of material.
- Use 1 cm thick lucite shielding when handling mCi quantities of material.
- For larger quanitites of material add 3 to 6 mm of lead to the outside surface of the lucite shield.
- Do not look into or work over and open container of P-32 without shielding.
- Conduct dry-run experiments to ensure dexterity and speed of handling P-32.
- Use remote handling tools to minimize skin exposure.
- Routinely monitor gloves for contamination and replace if highly contaminated.
- Urinalysis is required within 24 hours after working with 100 mCi or greater of P-32.
- Isolate waste in a labeled, shielded container.
- Dispose of radioactive waste in accordance with requirements in Appendix G of the Radiation Safety Manual.
