Two applications of beta spectrometry using active
gamma-ray discrimination are described. The beta spectra
of smears taken at a nuclear power plant at the end of a
300 day shutdown were characterized. The average beta
energy at "contact" (1.5 cm) was between 450 and 550 keV
for locations influenced by...
Large inelastic strain occurs inside a piece of lumber during drying. The strain consists of several components such as elastic, plastic, creep, shrinkage and mechano-sorptive effect. The mechanical behavior of the whole board during drying is determined by the behavior of individual strain components and their interactions. Whereas limited investigations...
