(3 & 4), pp. 241-249 .
Ultraviolet (UV) radiation can act on putative organic/biological matter at the Martian surface in several ways. Only absorbed, but not transmitted or reflected, radiation energy can be photo-chemically effective. The most important biological UV eff

It is well known that X-rays cause luminescence in quartz. This luminescence consists of two broad bands at 2.5 and 3.3 eV. After X-ray excitation natural quartz has an afterglow. The duration of this afterglow and the intensity of the emitted light

During X-ray irradiation of natural quartz a smoky colour is formed. After replacing monovalent interstitial cations with silver this smoky coloration is more sensitive to the dose of irradiation. Contrary to that, after an electrolysis with copper,

The temperature dependence of the luminescence of natural quartz induced by X-rays between 80 and 800 K is investigated. Using afterglow investigations, the temperature dependence of the low temperature luminescence is chiefly given by an activator l

The X-ray induced luminescence and its afterglow is investigated in natural and synthetic quartz crystals as well as in different types of glassy SiO2. In all types of SiO2 the luminescence intensity cannot be correlated directly with the impurity co
