The geophysical significance of the thin nitrate-rich layers that have been found in both Arctic and Antarctic firn and ice cores, dating from the period 1561–1991, is examined in detail. It is shown that variations of meteorological origin dominat

A series of glow-curve measurements were made to determine the general nature of the thermoluminescence of natural ice. The curves were made by subjecting the samples to ultraviolet radiation from a quartz-envelope mercury arc lamp while keeping the

The interaction of both the particle and photon component of the solar wind with the lunar surface material is expected to produce diverse chemical reactions. Experimental evidence for proton-induced OH formation was obtained by bombarding a glass, c

The theory of thermoluminescence as a function of temperature was tested by measuring the natural thermoluminescence of samples of limestone collected from several climatic areas. The agreement between the theory and the experimental results is satis

The permanent disposal of high-level radioactive wastes accumulating from the growing production of nuclear energy is of vital concern to the international community and needs a worldwide commitment to a solution to this problem. As the number of nat

Glow-curves of ice, made in the laboratory, have a distribution of peak-height ratios, with the maximum at approximately 0.75. The distribution was probably caused by varying conditions of crystallization, impossible to control with the present equip
