Calibration is 7 days from ship date. Use decay chart on back page to decay values to Calibration date. PACKAGING: Solvent is 0.5M HCl. SPECIFIC ACTIVITY RANGE: Calculated as Cr. STORAGE CONDITIONS: Store this product at room temperature. CONTAMINANTS: none detected PHYSICAL PROPERTIES: Decay Mode Half Life Principal Gamma Photon Electron Capture 27.7 Days 0.320 MeV (9.8%) Occupational Limits (based on most restrictive intake category: 10 CFR 20 U.S.NRC Regulations) Derived Air Concentration (DAC) Annual Limit on Intake (ALI) -6 8x10 µCi/mL 4 2x10 µCi DECAY CHART: To use the decay table find the number of days in the top row and left hand column of the chart then find the corresponding decay factor. To obtain a precalibration number, divide by the decay factor. For a postcalibration number multiply by the decay factor.

Wear extremity and whole body dosimeters while handling mCi (37 MBq) quantities. 51 Use shielding to minimize exposure while handling Cr. Use tools to indirectly handle unshielded sources and potentially contaminated vessels. 51 Prohibit eating, drinking, smoking and mouth pipetting in room where Cr is handled. Use transfer pipettes, spill trays and absorbent coverings to confine contamination. 51 Handle Cr compounds that are potentially volatile or in powder form in ventilated enclosures. Sample exhausted effluent and room air by continuously drawing a known volume through membrane filters. Wear lab coat, wrist guards and disposable gloves for secondary protection. Maintain contamination and exposure control by regularly monitoring and promptly decontaminating gloves and surfaces. 51 Use end-window Geiger-Mueller detectors, NaI(T1) detector or liquid scintillation counter to detect Cr. 51 51 Submit urine samples for bioassay at least four hours after handling Cr to indicate uptake by personnel. Cr is slowly eliminated from the body. Whole body counting provides a more sensitive method than urinalysis for 51 determining Cr body burdens. Whole body counting may be used occasionally to verify the urinalysis results. Isolate waste in clearly labeled, shielded containers and hold for decay. Establish surface contamination, air concentration and urinalysis action levels below regulatory limits. Investigate and correct any causes that threaten these levels to be exceeded. 51 On completing an operation, secure all Cr, remove and dispose protective clothing and coverings, monitor and decontaminate self and surfaces, wash hands and monitor them again.
