Abstract
On May 27, 2008, a strong earthquake of magnitude 5.3 Richter hit Zanjan province. The radon concentration has been measured and registered at the time of earthquake occurrence at 10:48 local time inside the Katalekhor cave being situated at suburb of Zanjan city. After this event, it was planned to measure and analyze the radon concentration in the same year (2008) and 10 years after the earthquake (2018) by using passive methods and the results have been presented. Real time observations show an increase of five times in radon concentration when earthquake happened comparing to normal condition.
