[ RadSafe ] Sellafield

[parthasarathy k s]

Under conditions of inversion, I have measured 10-20 times increases in the concentrations of the decay products of radon in air in Leeds, UK.My Ph D work itself was on the influence of airborne radioactivity on sensitive counting systems. Normal area monitors do not discriminate against natural radioactivity.Incidents such as this will enhance public insight on the relative importance of man-made and naturally occurring radioactivity. Even trivial increase in radiation levels in the west coast of USA is often wrongly attributed to the usual suspect, Fukushima releases

And the fact that this "routine" event triggered national news coverage just shows how "polarized" the news media is towards reporting issues with nuclear activities......

Do they report every time a fire alarm goes off?

For those that don't know, we've been suffering from heavy rain and low air pressure here in the UK. Almost certainly this drove increased radon release from the ground. Good to see that they still took it seriously. It hit the national news this morning.

According to http://www.newsandstar.co.uk/news/sellafield-shut-to-day-workers-1.1113620 :

"A radiation alert at Sellafield that forced the company to tell non-essential staff to stay at home was not caused by 'a nuclear event'. The elevated radioactive activity detected this morning by a perimeter monitor was caused by naturally-occurring background radon.  Standard weekend working operations will continue, with day staff due back in on Monday as normal, says the firm.  A company statement this afternoon said: 'Our in-air monitors are extremely sensitive and pick up on any abnormality. Overnight the monitoring system initially indicated elevated levels of activity. Following investigation and analysis, we can now confirm these levels to be naturally occurring background radon.'"
