Abstract
The accident at the Fukushima NPP has revealed a certain drawback of traditional methods of registration of ionizing radiation by means of the automated radiation monitoring system, because in the conditions of the accident at the NPP the monitoring posts of the system were damaged as a result of the tsunami (23 of 24), which did not allow to evaluate the degree of radioactive contamination of the area in the early stages. In such conditions the most promising method of radiation control carried out on the potentially hazardous area is a non-contact method using an unmanned dosimetry complex (UDC), the application of which would reduce the risk of exposure to additional dose loads of personnel carrying out search and reconnaissance work and, additionally, provide management not only with information regarding radioactive contamination of the environment, but also directly provide the results of the search and reconnaissance. However, apart from the equipment used to determine the radiation background (detectors, spectrometers, radiometers, etc.) an important part of the UDC is the organization of the dosimetry complex and the way of information transfer.A possible variant of data transmission channel from the dosimetry complex installed on the UDC to the operator's personal computer is presented using NRF radio modules as an example.
