The recently developed radon film-badge makes it possible to measure radon indoors, in soil, in water and/or in aqueous media (e.g. mud).

Radon air concentrations, normally high, increase more and more during the collector's floods. An explanation of this is a radon-water solubilisation process more effective in flood events, because of a greater rock-water contact surface.

In this paper measurements, results and model estimates, with reference to hydroelectric power plant noise emissions in the Aosta Valley territory, are compared in different contexts. The analysis was performed to evaluate and point out the influence of the noise source context on the accuracy of the model results. The estimates were implemented considering power plants as: point sources and area sources taking (or not) into account the building elements of the plant.

A modeling system for air quality assessment and management has been established and revised. The system has been used to evaluate the impact of traffic due to the re-opening of the Mont Blanc tunnel: the increase in NO(x) concentrations ranges from 50% at the bottom of the upper valley to 150% near to tunnel entrance.

In situ gamma ray spectrometry is an attractive method for providing information on the concentrations of radionuclides in the soil. This method requires separate knowledge of the soil density and of the radioactivity distribution relative to soil depth. In-field gamma spectrometry measurements were performed together with sampling of the soil at the same site for subsequent gamma spectrometry analysis in the laboratory.

Traditional sampling monitoring systems consist of collecting airborne particulate on filters; the sample is then extracted, purified and analysed. It is possible to identify each compound and to determine its relative abundance in the total particulate matter, on the other hand, this method requires great complexity of analysis.

The wide-band field detectors commonly used for environmental protection surveys do not make it possible to discern the contributions of the individual emitters at a given point. It is possible to obtain this result theoretically by using only a personal computer, and by using the characteristics of the emitter and of surrounding territory as inputs.

The electromagnetic field intensities in the vicinity of apparatus which generate RF fields are influenced by a multiplicity of variables which are tied to the conditions of their use. The setting up of proper ambient surveillance requires the predisposition of operational protocols which take variable factors into account, permitting the individualization of major risk situations, and assuring the repeatability and comparability of the results. To that end, in relation to a diathermy apparatus operating at 27.
