California’s Cell Phone Safety Guidance: 2017 vs 2009

January 4, 2018 (updated January 17, 2018)

In June, 2009, the Division of Environmental and Occupational Disease Control in the California Department of Public Health (CDPH) prepared a draft cell phone safety guidance document. Although the document reflected the consensus of the division, it was not released until May, 2017 pursuant to a court order--the outcome of a lawsuit filed under the California Public Records Act.

In December, 2017, the CDPH finally published their cellphone safety guidance document.

A side-by-side comparison of the contents of the original 2009 draft with the 2017 published version of the document appears below. The side-by-side can be downloaded at
