Least expensive beta emitter
NettetCarbon-14 is a low energy beta emitter and even large amounts of this isotope pose little external dose hazard to persons exposed. The beta radiation barely penetrates the outer protective dead layer of the skin of the body. The major concern ... •Expensive to purchase and to dispose of. Please order only necessary quantities. Detection: ... Nettetenergy beta emitter that can be quantified with a G-M pancake detector. The maximum energy (Emax) of the 14C beta is 156 keV, and a typical efficiency with a G-M pancake detector is about 4%. One of the highest energy common beta emitters is 90Sr-90Y ( Y E max = 2,281 keV), for which the typical efficiency is around 20%.
