Each certified firm and each certified individual, whether or not employed by a firm, and each testing firm employee may list no more than one name (under which the firm or individual intends to engange in radon activities), one phone number and one address in the Department's Radon Services Directory.
The list is prepared in alphabetical order and produced monthly.
Newly certified individuals and firms are listed in the month immediately following final certification.
The current list is available to the public upon request and accessible on the internet at www.depweb.state.pa.us (search term "Radon Services Directory") or via the Bureau of Radiation Protection's Radon Division webpages (direct link).
Persons certified, suspended, and decertified are published in the PA Bulletin on a monthly basis.
