The background of a hand-held alpha ZnS scintillation probe of 44 cm(2) was reduced from the normal 50 counts per hour (cph) to 4 +/- 2 cph and the efficiency increased to 34%. The limit of detection for a 30 min measurement is now 5 Bq m(-2) Po-210 on glass surfaces, corresponding to about 200 Bq m(-3) indoor Rn-222 exposure for 20 years. The probe was successfully used for retrospective determination of radon exposure. The probe is simpler, faster and more convenient, and more economic than alpha spectrometry or nuclear track detectors currently used in the field of lung cancer epidemiology and long term radon exposure.
