Each year a mussel produces an incremental layer of its shell composed mainly of calcium carbonate and a small fraction of organic substance. Many other elements are simultaneously deposited in these annual layers and are assumed to be essentially im

A discussion is given of the best choice of energy region and electron source for an energy loss study program with emphasis on chemical valence effects on stopping power. The particular role played by multiple scattering and bremsstrahlung is stress

Activation analysis by gamma spectrometry of manganese in pulp has been performed in the range 0·25–100 p.p.m. Test analyses show a maximum error in the manganese values of ±5 per cent. The manganese values for pulp obtained by chemical methods s

Gamma-emitting nuclides formed by neutron capture (and some other neutron reactions) can be identified by measuring the half-life and gamma energy preferably against a standard which might be the nuclide suspected. The uncertainty of these two proper

Methods for the accurate recording of energy loss spectra for electrons at a few MeV are discussed. Some experience with an electrostatic method is described. The method selected involves the variation of a portion of the current of the spectrometer

For the activation analysis of mercury, Hg 197 , with a 65 hr half-life, 68 keV X-quanta and 77 keV gamma quanta, has been selected. It was found that evaporation is serious even if certain precautions are taken. All samples were therefore sealed in

The adaptation of the Wernholm-Smars 5 MeV betatron for precise operation is described. Assembly, improvements and normal operation are described as well as a method for recording, by an XY -recorder, the spectrum of the electron line as detected wit
