Evidence of harm to children and teens living close to mobile phone masts includescognitive function impairment in teens… Meo et al Mobile Phone Base Station Tower Settings Adjacent to School Buildings: Impact on Students’ Cognitive Health 2018:   increased risk of diabetesMeo et al Association of Exposure to Radio-Frequency Electromagnetic Field Radiation (RF-EMFR) Generated by Mobile Phone Base Stations with Glycated Hemoglobin (HbA1c) and Risk of Type 2 Diabetes Mellitus 2015 Higher exposure to cell tower RFR was associated with delayed fine and gross motor skills, spatial working memory, and attention among adolescents compared to students exposed to lower levels of cell tower RFR. (13-16 years of age)     Students exposed to higher cell tower RFR had a significantly greater risk of type 2 diabetes mellitus (p = 0.016) relative to others exposed to lower cell tower RFR. High cell tower RFR was associated with elevated levels of HbA1c and risk of type 2 diabetes mellitus. (12-17 years of age)


Children are more vulnerable to RFR radiation Prof Tom Butler, On the Clear Evidence of the Risks to Children From Non-Ionizing Radio-frequency Radiation   
Morgan et al, Why children absorb more microwave radiation than adults: The consequences 2014   
Children’s health is at risk from everyday wireless digital technologies. Why? The past 15 years witnessed the proliferation of near-field microwave non-ionizing Radio Frequency Radiation (RFR) devices in the home, school and society. However, far field RFR from WiFi access points (AP) and routers, and at a wider level, 2, 3, 4 and 5G cellular telecommunications antennae, also pose significant risks, as existing scientific research indicates.  Children absorb more MWR than adults because their brain tissues are more absorbent, their skulls are thinner and their relative size is smaller. The fetus is particularly vulnerable to MWR. Responsible governments are passing laws and/or issuing warnings about children’s use of wireless devices    
Growing evidence to concern us about the threats of RFR on childrenSangun et al The Effects of Electromagnetic Field on the Endocrine System in Children and Adolescents 2015 Children are involuntarily exposed to various kind of non-ionizing radiation in their daily lives and are more sensitive to the effects. It is not easy to conduct a study investigating the effects of EMFs on a fetus or child due to ethical issues. Hence, the studies are usually performed on virtual models or animals. Although the results are conflicting and cannot be totally matched with humans; there is growing evidence to distress us about the threats of EMF on children. 
Exposure in utero to high levels of RFR associated with increased risk of ADHDDe-Kun Li et al Association Between Maternal Exposure to Magnetic Field Nonionizing Radiation During Pregnancy and Risk of Attention-Deficit/Hyperactivity Disorder in Offspring in a Longitudinal Birth Cohort  2020 Consistent with the emerging literature, this study suggests that in utero exposure to high levels of RF nonionizing radiation was associated with an increased risk of ADHD, especially ADHD with immune-related comorbidity. The findings should spur more research to examine the biological association of in utero MF exposure with risk of ADHD in offspring, given that almost everyone is exposed to it.
