Energy: Maximum: 1,710 keV; Average: 695 keV Half-Life [T½] : Physical T½: 14.29 days Biological T½: Bone ~ 1155 days; Whole Body ~ 257 days1 Effective T½: 14.29 days Specific Activity: 286,500 Ci/g [10,600 TBq/g] max. Beta Range: Air: 610 cm [240 inches; 20 feet] 0.76 cm [0.33 inches] Plastic: 0.61 mm [3/8 inches] II. RADIOLOGICAL DATA Radiotoxicity2: 94.7 mrem/uCi [Lung] & 15.5 mrem/uCi [CEDE] of inhaled 32P 29.9 mrem/uCi [Bone Marrow] & 8.77 mrem/uCi [CEDE] of ingested 32P Critical Bone [soluble Lung [Inhalation]; GI Tract [Ingestion - insoluble compounds] 32P]; Exposure Routes: Ingestion, inhalation, puncture, wound, skin contamination absorption Radiological Hazard: External Exposure [unshielded dose rate at 1 mCi vial mouth3: approx. 32P 26rem/hr], Internal Exposure & Contamination III. SHIELDING Shield with 3/8 inch Plexiglas and monitor for Bremstrahlung; If Bremstrahlung X-rays detected 32P outside Plexiglas, apply 1/8 to 1/4 inch lead [Pb] shielding outside Plexiglas The accessible dose rate should be background but must be < 2 mR/hr IV. DOSIMETRY MONITORING Wear radiation dosimetry monitoring badges [body & ring] if regularly handling mCi quantities of 32P V. DETECTION & MEASUREMENT Portable Survey Meters: Geiger-Mueller Wipe Test: Liquid Scintillation Counting is an acceptable method for counting wipe tests 32P VI. SPECIAL PRECAUTIONS - Avoid skin contamination [absorption], ingestion, inhalation, & injection [all routes of intake]. - Store (including waste) behind Plexiglas shielding [3/8 inch thick]; survey (with GM meter) to 32P
