ICRP considers that a dose limit of 2 mSv close to the body surface of a pregnant woman will ensure a dose limit of 1 mSv to the foetus. This assumption depends on the energy spectrum and composition of the radiation fields, especially those containi

The radiological problems associated with proton accelerators having maximum energies higher than a few GeV are discussed. Examples are given from accelerators where the authors have had practical experience for a number of years. The main focus will

We wish to report an equilibrium isotope effect from a nonhydroxylic solvent that is consistent with the electron-releasing nature of deuterium. EPR evidence indicates that the perdeuteriation of the most common anion radical solvent, tetrahydrofuran

Surveys of diseases and other forms of damage in naturally regenerated lodgepole pine were carried out in 1959 and 1962 near Robb, Alberta in an area that had been burned in May, 1941. Eighteen and one-half per cent of the trees on seven 0.05-acre pl

The interaction and absorption fragmentation parameters and mean free paths of heavyZ 3, cosmic ray nuclei have been measured in polyethylene (CH2) n and teflon (CF2) n . Within the statistical accuracy of these results it has been shown that pre

Measurements are reported of the major dose contributing components of the secondary radiation produced by the interaction of 7 GeV particles in external targets. Standard dosimetry techniques were used involving flux density determination from activ
