RIVM Report 749206001
The primary task of the National Radioactivity Monitoring Network (LMR) is the early detection of major nuclear incidents and the provision during such events of geographical information about the contamination. After a test period with a limited number of monitors, the LMR became fully operational in March 1990. This report is intended to give information concerning the operationality of the network in 1990. For the interpretation and presentation of the data, the "raw" data (ten-minute values as stored in the LMR database) are processed to mean values over an hour, day, week, month and year. For the validation of the data, restrictions are placed on the range. Additionally, in an averaging period at least 80% of the data have to be available and valid.
