This work is devoted to studying the alpha activity distribution of natural radionuclides in boarding schools located near zones tectonic faults. There are many faults Almaty and this basis for referring southern capital Kazakhstan radon-hazardous territories. As a result radiometric measurements 2D-topology alpha-radiation flux density from distance fault was found. Based on results coefficien...

Radiation monitoring and inspecting instruments are important tools for the measurement of radiation dose rate or radioactivity. Now in Taiwan, there are five laboratories (processors) capable of providing calibrations for radiation monitoring and inspecting instruments. All these five laboratories have been accredited by the Chinese National Laboratory Accreditation (CNLA). In the past, there ...

This paper presents development results of the method of seismoacoustic activity monitoring based on usage vibrosensitive properties of optical fibers. Analysis of Rayleigh backscattering radiation parameters changes, which take place due to microscopic seismoacoustic impacts on the optical fiber, allows to determine seismoacoustic emission sources positions and to identify their types. Results...

Solar radiation sustains and affects all life forms on Earth. In recent years, the increase in environmental levels of solar-UV radiation due to depletion of the stratospheric ozone layer, as a result of anthropogenic emission of destructive chemicals, has highlighted serious issues of social concern. This becomes still more dramatic in tropical and subtropical regions, where the intensity of s...

The global monitoring network of ground-based ozone measurements consists mainly of Dobson and Brewer spectrophotometers. These instruments provide total ozone column amounts derived from measurements of direct solar UV radiation. Analysis of total ozone measurements from the global monitoring network shows a nearly linear downward trend from 1980 to mid 1990s. Data after mid 1990s indicate tha...
