New Jersey Statutes Title 26. Health and Vital Statistics 26 § 2D-73

No person shall disclose to any person, except to the Department of Environmental Protection or the Department of Health, the address or owner of a nonpublic building that the person tested or treated for the presence of radon gas and radon progeny, unless the owner of the building waives, in writing, this right of confidentiality.

The provisions of this section shall not apply to a person performing testing or treatment on a building which he owns, or to instances where disclosure is necessary to contract for further testing or to contract for the mitigating and safeguarding of a building from the presence of radon gas and radon progeny. In the case of a prospective sale of a building which has been tested for radon gas and radon progeny, the seller shall provide the buyer, at the time the contract of sale is entered into, with a copy of the results of that test and evidence of any subsequent mitigation or treatment, and any prospective buyer who contracts for the testing shall have the right to receive the results of that testing.
