INLEDNING

I statens strilskyddsinstituts regi mäts kontinuerligt ga strålningen vid 25 platser i Sverige. Platserna är utmärkta på kartan sidan 3. Registreringen vid fem av mätstationerna, understrukna på kartan, utvärderas i nuläget med större nogg- rannhet än de övriga. Resultaten från dessa fem redovisas i föreliggande rapport.

Rapporten ger en redovisning av mätresultaten från 1982. Mät- resultaten ges i tabellform för dygnsmedelvärde, veckomedel- värde och månadsmedelvärde. Slutligen ges en tabell för den senaste femårsperioden för respektive mätstation. Som fram- går *v tabellerna är det variationer i mätresultaten under vi r«"halvåret. Detta beror i huvudsak på snötäckets dämpning

>rkstrålningen. För att lättare kunna jämföra mätresultat- et t från år ges i den sista tabellen förutom årsmedelvärde i- d medelvärde under dagar med barmark.

} k beskrivning av mätsystemet finns i arbetsdokument a 81-05, tgivet av statens strålskyddsinstitut.
