The development of an electret ion chamber modified for radon measurement is described and characterized. It is called an electret passive environmental radon Monitor (E-PERM)[trademark]*. The responses of two types of electret sensors and the E-PERM are reported. Their E-PERM precision was 4.8 percent. The result of blind-tests of 497 units submitted to the EPA Radon Monitoring Proficiency Program by 133 different E-PERM users are shown. The average accuracy of the E-PERMs tested was 11.4 percent. Costs per measurement are estimated and compared with other passive monitoring methods. EPERM evaluations from eight recent studies are summarized. The results demonstrate that this new type of radon monitor is well suited for measuring radon in homes.
