The outdoor and indoor measurement of natural gamma radiation in Zanjan province (Iran) was made using a Geiger–Muller dosemeter. The average outdoor and indoor dose rates were determined as 127 ± 20 and 135 ± 23 nSv h–1, respectively. The average annual effective dose was calculated as 0.82 mSv, which is more than the same value worldwide.
