Physico-chemical properties of radioactive particles of nuclear explosions

The analysis of the experimental data published in open press has been made in this work. At present time it is known that 118 atmospheric nuclear explosions were conducted at Semipalatinsk test site of which 30 were above-ground (5 charges failed to go off) and 88 - air and high-altitude. Since August, 1991 Semipalatinsk test site has been closed for nuclear weapon test and therefore it is only in the world, unique naturally laboratory for study the nuclear test effects on the environmental and biological objects. An attempt to systematic the results of the experimental researches on radioactive particle study, held by some authors for the first time was made in this work. Short methodic principles of study of different properties and characteristics of radioactive particles, formed during the nuclear explosions of different form and types are given
