Material from a new batch of beryllium-7 (Be-7) will be available through the U.S. Department of Energy Isotope Program (DOE IP) in mid to late September. This gamma-emitting radionuclide (477.6 keV) is most commonly used for environmental studies such as sediment radiodating but has also recently been used by the nuclear physics community to investigate the origins of the universe.
The relatively short-lived Be-7 (t1/2 = 53.22 days, decays to lithium-7) is produced using the DOE IP’s proton accelerator at Brookhaven National Laboratory via a 16O(p, spall)7Be reaction in the Brookhaven Linac Isotope Producer (BLIP) cooling water. The Be-7 product has a radionuclidic purity of >95%, with a radiochemical concentration of >1 mCi/mL in 0.5–5.0 N HCl.
Be-7 is produced by the DOE IP only upon special request. For further inquiries about the availability of Be-7, Contact the NIDC or Request a Quote for Beryllium-7.
