Poor old Len, all agitated about double blind mast effect experiments.
Perhaps he should try the following experiment: -
A room has an aperture on the other side of which can be: -
nothing (control)
sun (~1G5m away)
nuclear reactor (~10m away) or large lump of Cobalt60 / X Ray machine
1Kw Microwave (open cavity)
phone mast (~100m away)
The question is can a human subject detect whether there is anything there,
can they tell if damage is being incurred, and will they be damaged?
Detect Damage Detect Damage
nothing N N N
Sun Y Y Y after
1,000s depending on skin
Reactor N Y N
1kW mwave Y (10s) Y (macro) Y after 100s
Phone Mast N N N
So Len would be right - people can't detect electromagnetic radiation,
unless they have receptors (eyes), it causes macro effects (such as
heating), or therapeutic effects, such as burns.
Sun
Has an incident energy level of 1 - 2 kW/sqm, which can cause general
heating and heatstroke. More seriously sunshine contains ionising ultra
violet radiation. Humans can be permanently or temporarily adapted to
resist the effects (melanin), but unadapted subjects will experience second
degree sunburn in under an hour and much increased risk of skin cancer
(melanoma) after repeated lower level exposure. All humans can readily
detect sunshine and sunburn and will normally [learn to] avoid further
exposure when damaged and afterwards.
Reactor / X Ray / Gamma Ray source
Unless the energy flux is very high humans will not be able to detect the
ionising radiation or the damage it causes. In high doses subjects may
experience radiation sickness (bruising, hair loss, general illness), in
lower doses cancers may form in the long term.
Microwave Oven
Human tissue readily absorbs microwave radiation, causing local or general
heating. Although the micro waves can't be detected, the localised heating
and burns would be detected and typically subjects would move away from the
apparent source, in the same way as they would move away from an open
furnace door. The damage would essentially be macro (cooking), although
some more delicate structures (such as the cornea) could suffer long term
damaged due to a long term lower level of flux (like you can cook an egg on
a hot car bonnet).
Phone Mast / Wi-Fi
A typical mast emits a maximum of 25W omnidirectionally and the flux at 100m
is a few micro watts per square metre. Which would be undetectable by
humans. Whilst you might just notice a warm ear lobe from prolonged use of
a 'high' power [1W phone] transmitter held close to your ear for a long
time, even this level of flux of non ionising radiation can only cause
damage in your imagination.
Of course Lenny's obsession with this might be anecdotal evidence that his
imagination, judgement or reasoning has been damaged.
