WOW getting technical now - so with my basic maths would I be right in calculating:
Number of hours in a year is about 8766 hours
Number of microsieverts in a year would be 8766 x .67 = 5873 microsieverts
Divide by 1000 to get to millisieverts = 5.873
so........you could sit next to one of these every hour all year and still only be exposed to a quarter of the permitted dosage of a radiation worker.
It puts it all into perspective.

My understanding has always been that the risk of Radiation poisoning is minimal, you are more at risk from "Heavy Metal poisoning" as you would be from Lead, Mercury etc. I handled quite a lot of the raw material delivering it to ROF Birtley and still have the warning Placard that was carried in my Cab.
