This work is related to development of a new type of fog sensors and measurement devices. We study fogs, their properties, and especially their ability to clean different contaminants from the air, such as chemical, biological, radiological and nuclear (CBRN) agents. In that sense, fog can be used for effective counteraction to terrorist attacks and for prevention of industrial accidents and disasters. In this paper, we present the possibility for measurements of fog parameters using the Surface photo-charge effect (SPCE) and some results obtained in that way concerning size and speed of droplets. Knowledge of these fog parameters is important in order to gain a more practical insight about the optimization of the penetration and cleaning properties of fogs used for large scale decontamination.

An analysis of the main radiological warfare agents and of the different types of detectors for them is performed. The basic principles of the most common detection methods are described. The aim of the study is to outline the main challenges in this field. The possibility for applications of the Surface photo-charge effect in the field of detection of radiological warfare agents is discussed. An emphasis is put on the simulation of the radioactive substances during the performing of experiments.
