Large scale monitoring of radioiodine in thyroid: equipment and preparedness in the Czech Republic

Original language description

In the case of an accidental release of 131I, a system for large-scale monitoring of the population for the radionuclide intake is needed, which has been recognized by various national and international initiatives. In the Czech Republic, the monitoring is ensured by SÚRO (National Radiation Protection Institute) in the frame of the Radiation Monitoring Network. Arrangements for the involvement of third parties, namely nuclear medicine departments, are also made. For a proper assessment of the thyroid dose in population, a monitoring system is required to be capable of measuring adult as well as child subjects across a wide range of ages. Such system has been developed by the Institute and the company Envinet, a.s. NUVIA Group. Six gamma-ray spectrometry scintillation units equipped with collimators are connected to at least two subject registration sites. Barcode and RFID readers built in the measurement units facilitate matching the subject and measurement result in such multiunit detection system. In order to achieve up to thousand subjects to be counted within one day, two- or treeminute measurement time is sufficient for the detection of 100 Bq of 131I in thyroid in non-elevated ambient background. In the paper, general considerations, monitoring system and its performance are presented, together with a scenario of an exercise for the evaluation of measurement capacity.
