I picked up further information from Maurice Walsh about safety
of water stored in hot water tanks, particularly concerning
Radon. This
further to his report<span style="font-family: Arial;

"Radioactivity in drinking water supplies in Western
Australia".</span></span></p>

tanks? <br>
<br>
Yes.
However, from a radiological point of view, it really depends
upon the amount
of radioactive elements that are in the incoming water source,
i.e. radium
isotopes. Radon-222 (a radioactive gas and progeny of
radium-226) is
believed to be released mainly in the bathroom when water is
released from
shower roses. Thus <b>if</b> the water source has a high in
radium-226 content then
the radon-222 released may be high as well. Thus <b>if </b>hot
water for the household
is not stored within tanks and the water is heated via
an instantaneous hot water unit then the level of radon-222
could be
the at the same level as water stored within tanks. The best way
to rid the bathroom of radon and the rest of the home is to
ventilate – install exhaust fans and open windows. The
radium isotopes are only harmful if ingested for long periods.<br>
