# RF-041 — Yale prenatal handset mouse experiment with acknowledged dosimetry limits

Why this matters
After exposure during pregnancy, mouse offspring showed altered activity and object recognition. Developmental outcomes deserve attention, but the experiment did not measure how much RF energy the mothers or fetuses absorbed. Its published hormone correction is retained; these results do not establish ADHD or a human prenatal risk level.

Exposure: Muted/silenced 800-1900 MHz-rated phones on active calls during gestational days 1-17, 4.5-22.3 cm from mice; deactivated-phone controls. The stated 1.6 W/kg is the phone rating, not measured maternal/fetal SAR.

Design: 33 exposed and 42 control pregnant mice. Object-recognition testing in 161 offspring (82 exposed,79 control); blinded behavioural observers. Prefrontal electrophysiology used prenatal protocols of 0,9,15 or 24 h/day.

Finding: Exposure-associated hyperactivity, reduced object recognition and altered prefrontal glutamatergic synaptic transmission were reported.

Statistics: Original Results: cumulative object-recognition preference 63.0% exposed versus 69.9% control, P=.003,n=161. Light/dark transitions 24.4 versus 16.4,P<.001.

Boundary: Authors explicitly acknowledged unmeasured exposure and no traditional calibrated EMF generator. Maternal/fetal dosimetry absent; offspring/neuron counts are not independent dam counts. Not proof of human ADHD or below-limit prenatal injury.

Related: Yale programme, independent from UK Broom 2019 but substantially different exposure protocol.

Protection Question: Are the developmental changes reproducible under measured maternal and fetal exposure? Uncalibrated handset exposure and litter-level uncertainty prevent a quantitative prenatal protection claim or a human ADHD inference.

Access: Original eight-page PDF, including appended 2013 corrigendum, reviewed. Scite notice confirmed.

Notice: 2013 corrigendum DOI 10.1038/srep01320: corticosterone ELISA repeated using stored serum; control 5.4 versus exposed 6.1 ng/ml, P=.786, n=6/group. Authors state conclusions unchanged.
