WebAlthough phosphorus ( 15 P) has 22 isotopes from 26 P to 47 P, only 31 P is stable; as such, phosphorus is considered a monoisotopic element. The longest-lived radioactive isotopes are 33 P with a half-life of 25.34 days and 32 P with a half-life of 14.268 days. [3] [4] All others have half-lives of under 2.5 minutes, most under a second. WebExposure to white phosphorus should not exceed 0.1 mg/m 3 (8-hour time-weighted average per 40-hour work week). White phosphorus should be kept under water (as it is …
