Wired ear-pieces are NOT safe unless they are specifically shielded against
electromagnetic radiation. Wearing an ear-piece connected by a wire to a mobile
phone in essence converts the user's head into an antenna for the base-station.
• Home-based cordless phones do not emit as much electromagnetic radiation as
conventional mobile phones, however they are NOT to be regarded as being
safe owing to the longer usage time (typically cheaper calling rates) associated
with home-based calling plans. Using such phones for less time and on "speakerphone"
mode with the cordless phone held at least 20 cm from the head is a
safer alternative to holding them close to the side of the head.
• "Walkie-talkies" are NOT safe. They emit very high levels of electromagnetic
radiation, up to 50 times more than a mobile phone.
• Keeping a mobile phone close to one’s head overnight is NOT safe. Even "at
rest", the mobile will regularly emit a pulsed microwave signal to its closest
base station in order for the mobile phone's position to be tracked in order to
maintain its expected service.

Mashevich and colleagues exposed human white blood cells to 830 MHz
electromagnetic fields, exposure occurring for 72 hours with specific absorption
rates (SARs) of 1.6 - 8.8 W/kg (per the US FCC, the current maximum SAR for
the head is 1.6 W/kg). They found a dose-response of cellular/genetic
abnormalities, namely a linear increase in chromosome 17 aneuploidy (a major
"somatic" mutation leading to "genomic instability" and cancer), the degree of
aneuploidy increasing with SAR. They concluded that, per their experimental
model, "the genotoxic effect of the electromagnetic radiation is elicited via a
non-thermal pathway" Tweet
