I think the author has done a great job writing this series and I can't wait to read the third and fourth World of Norm books. This radon comes from the ground, with exposure affected by factors such as local geography, building construction, and lifestyle.

The minerals in the sands are subject to gravity concentration, and some concentrates are significantly radioactive, up to 4000 Bq/kg. Enhanced radionuclide concentration in coal tends to be associated with the presence of other heavy metals and high sulfur content.Because radon is so short-lived, and alpha-decays to a number of daughter products which are solid and very short-lived, there is a high probability of its decay when breathed in, or when radon daughter products in dust are breathed in.

Exposure from the nuclear fuel cycle - including fallout from the Chernobyl accident - accounts for less than 0. Analysis of oil and gas from many different wells has shown that the long-lived uranium and thorium isotopes are not mobilized from the rock formations that contain them. His brother was being bullied and didn't want to tell his parents , like who doesn't tell their parents if theirs a problem. Norm knew it was going to be one of those days when he woke up with a half-Polish Cockapoo on his head.Over the years there have been many occasions when it was asserted that coal-fired power stations emitted more radioactivity into the environment (from NORM) than was released anywhere in the nuclear fuel cycle. The list of isotopes that contribute to natural radiation can be divided into those materials which come from the ground (terrestrial sources – the vast majority) and those which are produced as a result of the interaction of atmospheric gases with cosmic rays (cosmogenic).

BOOK OF THE MONTH - A heart-warming and hilarious story told in 25 chapters, perfect for the countdown to Christmas. Decommissioning experts are increasingly concerned about double standards developing in Europe which allow 30 times the dose rate from non-nuclear recycled materials than from those out of the nuclear industry. This funny illustrated book is an accessible read likely to find favour with fans of Wimpy Kid, Big Nate and Tom Gates.

In 2016 the government announced that material with less than 8 Bq/g caesium would no longer be subject to restriction regarding disposal. Higher concentrations may be found in zirconia (zirconium oxide), which is produced by high temperature fusion of zircon to separate the silica.
