Hello, I am just breaking into the home inspection business and wanted to get various opinions regarding which method I should use to test for radon. Seems to me that the most cost effective way is the kits available from a variety of companies. My biggest concern about the continuous radon monitor is the initial cost and any cost associated to calibration. Also, I’m not too keen on the idea of leaving an $800 piece of equipment unattended in someone’s home for two days. All opinions/suggestions are welcome.
