Keywords: Wet deposition; weather radar; Chernobyl; nuclear accidents; 137Cs

Abstract: Deposition of radionuclides from the Chernobyl accident depended critically on patterns of precipitation intercepting the material. This paper describes the use of the RAINPATCH model to calculate wet deposition of 137Cs over England and Wales. This puff-based model makes direct use of precipitation data measured by weather radar to determine the scavenging of airborne material. The detailed spatial and temporal resolution of when and where material was scavenged provides good agreement with measurements. Since all the data used could potentially have been available at the time, such methods could usefully be applied in real time in the event of any future accident releasing such radionuclides.

Empirical scavenging coefficients of radioactive substances released from chernobyl

Title: Empirical scavenging coefficients of radioactive substances released from chernobyl

Author: Kirsti Jylhä

Reference: Atmospheric Environment. Part A. General Topics, Volume 25, Issue 2, 1991, Pages 263-270

DOI: http://dx.doi.org/10.1016/0960-1686(91)90297-K

Keywords: Chernobyl; radioactive fallout; wet scavenging coefficient; weather radar; Finland

Abstract: After the accident at the Chernobyl power plant on 26 April 1986, most parts of Europe were affected by the associated radiation pollution. In this paper the dependence of the precipitation scavenging coefficient λ (s−1) on the rainfall rate R (mm h−1) is studied on the basis of radioactivity and radar rainfall measurements in Southern Finland after the accident.
