Lead-210 and Beryllium-7 fallout rates on the southeastern coast of Brazil

Total 210Pb and 7Be fallout rates were measured on the coastal region of Niteroi, Brazil. The monthly depositional flux of 210Pb and 7Be varied by a factor of 26, from 1.7 to 43.3 mBq cm −2 year −1 and ∼27, from 7.5 to 203.5 mBq cm −2 year −1, respectively. The relatively large oscillations in the d...
