RadaLink is a time versus money thing. Some choose to use their time. I choose to use my money. I give them money becuase I have better things to do with my time than maintain worker exposure records, quality control records, machine calibration records, machine calibratiions, standard operating procedures, etc, etc. RadaLink makes my radon testing painless and profitable and they provide great back up when I need it. And, it puts a nice chunk of change in my pocket. I share a small chunk of that change with them to take the paperwork load off my back. Money or time. To each their own! -
