The necessity of remote monitoring the radiological situation in the different areas of nuclear power plants, adjacent territories, etc. is sustained. One of the most important conditions for this control is the duration of the system work (for ten or more years) without human intervention (only in a special case). It is noted that a feature of this environmental monitoring for the presence of radiation is the ability to transmit information over long distance in real time without distortion. And constant receipt of information about the value of the exposure dose in the sensor area is also important. In a case of using the system of a large number of sensors, there are no problems information processing, because it is contained in the optical signal. The design of the fiber optic communication line with using the fiber optic sensor is proposed. The measurement limits of the exposure dose of radiation are marked. The results of experimental researches of various fibers for using in these sensors are presented. The method of radiation control with their use is determined.

It has been substantiated that the most stable source of energy at any time are nuclear power plants and hydroelectric power plants. It is noted that these sources of electric power generation are the most dangerous in the event of an emergency for nature and humans. In addition, nuclear power generates dangerous sources of pollution during its operation. The article compares the levels of pollution emanating from traditional energy sources and nuclear power plants.

We studied the efficacy of seed treatment with a variety of fungicides for control of root rot of wheat in different soil types. The effectiveness of various doses of the preparation on the basis of thiram (TMTD and TMTD-plus) and triazole containing Dividend Star, SC has been compared under the conditions of the Southern Urals in typical soils of the region (dark chestnut, southern chernozem, common chernozem). It is revealed that the effectiveness of thiram containing preparations in moderate doses (2.0–2.5 l/t for TMTD-plus and 3.0 l/t for TMTD) is higher on the dark-chestnut soils than on Chernozem. The biological efficiency of the Dividend Star does not depend on the type of soil. We compared the five pesticides with active substances from different chemical classes: Celest Top (thiamethoxam + difenoconazole + fludioxonil), Scenic Combi (clothianidin + fluoxastrobin + prothioconazole + tebuconazole), Maxim (fludioxonil), TMTD-plus (thiram), Kinto Duo (triticonazole + prochloraz) and Dividend Star (difenoconazole + cyproconazole) at the different tillage technologies under the non black soil region conditions. The effectiveness of all preparations decreases significantly at the no-till technology compared to the plowing. Most effective in plowing were Kinto Duo, Celest Top and TMTD-plus, and in zero-till – Celest Top and Scenic Combi.
