OPERA observatories of environmental radioactivity in France
 |  |  |
| Abstract | The OPERA-AIR air-samplers network insures the radiological monitoring of the atmosphere in various locations of the French territory. A station consist of continuous air sampler that allows to retain aerosols on a filter. A charcoal cartridge can also be used for gazes if necessary. The filters and cartridges are regularly changed and sent to IRSN laboratory for analysis. One can find two different types of samplers in the OPERA-AIR network: 8 samplers with very high air sampling rate (800 m3/h), for very low level measurements, and 40 samplers with medium air flow rate (80 m3/h), more dedicated to the monitoring of radiological events that could occur in France. A modernization phase of the medium flow rate samplers has begun in 2012 (end in 2015), that consists of new sampling devices and new implantation strategy. | |
