Intensification of technological processes, based on the latest achievements world of science and technology in industry, is one of the most pressing problems in many sectors of industry - including agricultural process that use the process of dehydration. World technical progress, on one hand, offers possible ways for this problem to be solved - yet on the other it exacerbates the problem, since numerous negative factors become involved. The issue of environmental security equipment and personnel is of particular importance, as well as environmental control in which electric fields are used as a control method. Author(s) Details V.

Aims: The dangerous portion of ultraviolet radiation is widely believed to be completely absorbed by the atmosphere before reaching Earth’s surface. Our objective is to make multiple measurements at Earth’s surface of the solar irradiance spectrum in the range 200-400 nm. Methods: We made numerous measurements of the solar irradiance spectrum in the range 200-400 nm at an elevation of 56 m with International Light Technologies ILT950UV Spectral Radiometer mounted on a Meade LXD55 auto guider telescope tripod and mount assembly. Results: Our multifold measurements of solar irradiance spectra demonstrate conclusively that all wavelengths in the spectral range 200-400 nm reach Earth’s surface, contrary to the widespread perception that all UV-C and the majority of UV-B never reach the surface. We confirm the surface UV-C measurements of D’Antoni et al. (2007) that were disputed, based on faulty computer model calculations of atmospheric ozone, and thereafter ignored by the ...
