1. "Câmara de ionização aplicada a medidas de altas taxas de dose." / Ionization chamber for high dose measurements
Industrial gamma irradiators facilities are designed for processing large amounts of products, which are exposed to large doses of gamma radiation. The irradiation, in industrial scale, is usually carried out in a dynamic form, where the products go through a 60Co gamma source with activity of TBq to PBq (kCi to MCi). The dose is estimated as being directly

2. Técnica do Pulso Eletroacústico para medidas de Perfis de Carga Espacial em Dielétricos / Electro-acoustic Pulse to Measure Space Charge Profile in Dielectric Materials
It is described the implementation of the electroacustic pulse technique, PEA, for the determination of space charge profiles in dielectrics. The method is based on the acoustic signal generated by the application of a voltage pulse with short duration on the sample. The acoustic signal generated by pulse is detected by using a piezoelectric transducer coupl

3. Mortality and incidence of cancer among oil exposed workers in a Norwegian cable manufacturing company. Part I. Exposure conditions 1920-79.
Heavy high viscosity oils, transformer oils, and very light low viscosity oils have been used in a Norwegian company in the impregnation, sheathing, and installation of paper insulated cables. The aim of the present study was to determine exposures to oils and other chemicals at these workplaces from 1920 to 1979. Oil mist was sampled on glass fibre or membr
