Beyond developing their camping skills, participating in a food drive to aid the hungry and donating pajamas for seniors, Girl Scouts across America this year were offered a new way to earn a special uniform patch: learning about the wonders of 5G cellphone technology and, in some cases, promoting it. The opportunity came courtesy of Ericsson, the Swedish telecommunications giant, which sponsored the "Ericsson Limited Edition 5G & IoT" (Internet of Things) patch program. The program, still available on at least one Girl Scout website, targets all age levels, from Daisies (kindergarten-age Scouts) to Ambassadors (those in high school), with an array of activities intended to "introduce Girl Scouts to 5G and the Internet of Things." Scouts of all ages are invited to "discuss with your troop or an adult how mmWave spectrum is safe and does not cause harm to our health." Health experts, who are concerned that wireless radiation poses a health risk to children, criticize the Ericsson program as an improper and inaccurate form of industry marketing. "Anytime corporations advertise directly to children, I'm very suspicious," Dr. Jerome Paulson, a pediatrician ... told ProPublica. "It would be like Exxon Mobil sponsoring a patch on climate change." The Environmental Health Trust, an activist nonprofit ... recently sent a letter of protest to the Girl Scouts' national office, saying the patch materials "misleadingly state that 5G networks and cellphones are safe," and urging their removal from all Girl Scout websites.
