Mar. 23, 2023 / A major peer-reviewed publication reports that many aspects of child development can be affected by radiofrequency “wireless” radiation, and screen time.

Leading international scientists find impacts on bonding, speech acquisition, behaviour, socialization, learning and addictions. Cancer risks are also increased.

Recommendations include use of wired technologies, that wireless radiation exposures be “ALARA” (as low as reasonably achievable), that physicians query use of tech in well-child visits, and research to prevent and investigate electrohypersensitivity.
