Dear Public Health England,

Dear PHE,
Please disclose the following information:
-Do you hold information on the effects of fracking on radon
release and distribution in areas where fracking has taken place?
This does NOT apply to wellhead data, rather to surrounding areas
distant from the wellhead.
- Do you have plans to monitor changes in radon levels at the
surface in such areas on a prospective basis after fracking has
commenced?
- Do the fracking licences require fracking companies to survey and
monitor ambient environmental radon levels in areas overlying and
adjacent to their activities?
- Radon is capricious in distribution, and can track along
geological faults to produce anomalously high concentrations in
some properties, whilst leaving adjacent ones unaffected ("radon
hot spots"). Since fracking involves the creation of myriad
microfaults which would facilitate such a process, what plans do
you have to ensure that such redistribution, threatening previously
unaffected properties, does not occur?

- Has PHE formally considered these matters and made an evidence
based risk assessment? If so, where can this be found? If not, does it have plans to ask COMARE to
produce a supplement to its radon report considering these issues,
and if not, why not?

Many thanks for your kind assistance,

Yours faithfully,

R. Baillie
