PITTSFIELD, Mass. Local health officials are disappointed with the state Department of Health for backing out of an investigation of health concerns related to a Verizon cell tower at 877 South St. On Wednesday, the Board of Health approved an alternative action plan to procure a firm that specializes in the measurement of radio frequency radiation to determine if the tower is in compliance with 47 CFR 1.1310 or federal radio frequency radiation exposure limits and will be advocating for the affected neighborhood to Gov. Charlie Baker and the Legislature. The Environmental Toxicology Program at Mass DPH offered its assistance in listening to residents concerns after the Board of Health said it doesn t have the expertise to investigate on its own. Mass DPH has since broken the agreement, according to board members.
