Abstract

The intelligent detector for radioactive particles spread over large geographical areas refers to a method and a system for real-time detection of the presence of radioactive particles in the environment, interconnecting the universe of bees with self-organizing capabilities as a carrier and transporter of radioactive particles with the universe of computers which processes information on their presence and nature and sends alert messages in case of radioactive contamination. It contains a local computer network with ionizing radiation sensors (GM and SiPM), a weather micro-station module used to estimate the direction of movement of radioactive particles, a GPS module used to obtain information on the geographical location of the detector, a GSM module used to transmit alert messages in case of radioactive danger, a photovoltaic power supply module used to ensure energy autonomy. Experimental system use Layens beehives with 20 frames (440x340mm wide) and more than 70 000 bees and is located in the area of uranium mining in Tulghes-Grinties, Neamt County . The Layens hive is for successful overwintering and rapid spring colony buildup even in the cold climates in Romania. Acording L'Abeille de France : 'Layens hives are wonderfully suited for remote outyards. In the yards that I visit only once per year, I always find the bees in excellent shape with the hives full of honey, harvesting which becomes my sole task'. As environment bioindicator is an excellent/robust sensor. Local computer nework is bassed on Embedded Linux Machine with ARM processors. The project has been expanded with educational facilities to help researchers/teachers and students from Romania to participate at IAEA Research Activities or UNESCO-Guerlain program ..
