A portable battery-operated instrument, the radometer, which permits rapid measurements of environmental levels of radon/thoron is described. The radometer measures radon and thoron by electrostatic collection of charged progeny on a surface barrier detector. Accurate measurements are made in only a few minutes because this instrument uses a dual electric field configuration, thus eliminating filters which slow the response time. An onboard computer corrects for the effect of moisture and previous deposition to maintain accuracy and fast response when the instrument encounters high humidity and/or rapid changes in concentration. The instrument's detection volume is 6 L and its efficiency is 25% or .041 cpm/Bq m-3 (1.5 cpm/pCi L-1 ). The instrument has been tested extensively, and its operation is very reliable
