The processor is 15W. That's the lowest processor in the 300-series.
The processor has an NPU (50 TOPS). I don't expect the NPU
will get to run for very long, before it and the CPU portion
are thermally throttled (clock-rate reduction, instruction-rate
reduction).

Microwave radiation is no joke, and we seek to remove it in situations
where it is avoidable.

If you hold a smartphone to your head for long periods of time,
that can lead to a "glioma". But the cancers are also naturally
occurring and can occur in pediatric situations.

   "A brain glioma is a tumor that starts in glial cells, the brain's
    supportive tissue, and can occur in the brain or spinal cord,
    varying from slow-growing (low-grade) to aggressive (high-grade)."

Some of those are operable.

Your hands are not your brain, they're a different kind of tissue.
Your hands contain bones, muscles, nerves, skin. You will notice your
hands are already susceptible to cancer, such as skin cancer from
the sun (melanoma).

The smartphone is more likely to need to use a bit more RF power to
reach a tower. In a business (where these keyboard computers would
be used), there could be a 4G microcell inside the building (as office
buildings with a lot of metal, don't have good RF penetration
for services). This means the smartphone automatically becomes less
dangerous, because it can turn down the transmitter when it senses
the tower (microcell) is "really close".

The Wifi is the same situation. Using Mesh Wifi in a business, the
active element can be in the same room with you, and the keyboard
can turn down the Wifi transmitter because it senses how close it is to the
other receiver. The Wifi power level, will be lower than it is in
your house right now, where the router is in the other end of the
house.

The keyboard is not pressed against your head.

I think you're safe.

I don't leave Wifi running here, that is not performing a function.
Right now, the (intentional) 2.4GHz level in the room here is zero.

I don't think that keyboard has an Ethernet port, but you can
add one (ASIX USB to Ethernet). You could also reach into the unit,
and unplug the Wifi module. Because the keyboard only has two connectors,
that's one of the major reasons I would not buy one! It should have
more connectors, for user convenience. Three ports is a minimum.
