Abstract
The NEMO 2 detector consists of a tracking volume to reconstruct electron trajectories associated with plastic scintillators. The purpose of the R and D is to aid in studies of neutrinoless double {beta} decay. Using the first nine months of data from the NEMO 2 detector, a method of measurement of the {sup 208}Tl and {sup 214}Bi radiopurities is presented. These isotopes contribute to the background in the 3 MeV region corresponding to the Q of 2{beta}(0{nu}) for molybdenum. The channel 1e1{gamma} is used. Monte Carlo simulations with GEANT give the corresponding efficiencies. Radiopurities for a standard Molybdenum foil and for two high purity molybdenum samples have been measured. The results are in good agreement with {gamma}-spectroscopy measurements using an HPGe crystal. 2000 hours of data yields a sensitivity of .3 events/min/kg.
