Opis:: Wireless system for radiometric measurements contains probes, for gamma radiation measurements and other probes for radon concentration measurements in air and water. The probes have the form of droplet-tight cylinders powered from a local battery. Measuring data collecting unit, based on a portable computer, communicates directly with the probes in a wireless manner using the WiFi communication network, or through the internet using mobile phone GSM network. Serial port wire connection is also possible. The local battery ensures at least 14 days of continuous operation of the probes. For long term measurements, the probes can also be powered from solar panels. Construction and operation of the probes are described. Results of scintillation probes investigation are given. Detection efficiency of the developed probes is comparable with the laboratory probes offered in our country.

Opis:: A system for measurements of particulate matter in the ambient air, employing beta absorption instrument AMIZ-2007 with wireless communication facilities based on GPRS technology, is presented. Uncertainty of measurements caused by the counting statistics was analyzed and it was found that at least 3 h of sampling time is needed to achieve coefficient of variation lower than 20% for the average concentration of particulate matter in the ambient air exceeding 10 μg/m3. Application of a C-14 beta ray source instead of Pm-147 improves sensitivity of the measurement ca. two times. Some results of on-line operation of the system with PM10 and PM2.5 samplers are also shown.
