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. Table 4 gives the characteristics of NORM produced during oil and gas extraction and some indicative measurements of concentrations. Exposure from the nuclear fuel cycle - including fallout from the Chernobyl accident - accounts for less than 0. its all about a boy who has moved from his old big house, and into a new small shed like house, norm hates it, the front garden isn't big enothe to do stunt on his bmx. Coal can be mined in either open pits or underground mines, and produces a significant amount of waste rock, and drainage water that can present with elevated levels of radioactivity.

Cosmogenic NORM is formed as a result of interactions between certain gases in the Earth’s atmosphere and cosmic rays, and is only relevant to this paper due to flying being a common mode of transport.I haven’t read the first book in the series, but found it didn’t matter as it is easy to relate to the characters in the book. The release of radionuclides in the off-gas was much greater than the amount contained in the fly ash. However, the solid decay products then contaminate gas processing plants, and this manifestation of NORM is an occupational health issue, as discussed above. If the scale has an activity of 30,000 Bq/kg it is 'contaminated', according to Victorian regulations. For comparison, the average radioactivity of the Earth’s crust is about 1400 Bq/kg, more than half of it from K-40.

Radioactive materials which occur naturally and where human activities increase the exposure of people to ionising radiation are known by the acronym 'NORM'. I would recomend this book because at first i wasn't interested in comedys but when i read the blurb of the book it was oustanding and i couldn't wait to read more. 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). Levels in Scandinavian homes are about double the US average, and those in Australian homes average one fifth of those in USA. This means that for Ra-226 scale (decay series ofnine progeny) the level of Ra-226 itself is 3300 Bq/kg.It decays (through several rapid steps) to Pb-210 which can therefore build up as a thin film in gas extraction equipment. Meres combines great humour with a portrait of boy whose response to trauma is to ignore it, and also shows how embarrassment and shame can cause us all into unwise decisions. BOOK OF THE MONTH - A heart-warming and hilarious story told in 25 chapters, perfect for the countdown to Christmas. Norm is devastated that his family have down-sized their house, his father has no job, and his younger brothers seem to receive preferential treatment. But then again, you can't blaim unfortunate Norm, even if he gets caught doing a wee in his mum and dad's closet!

It is found in many foodstuffs (bananas for example), and indeed fills an important dietary requirement, ending up in our bones.The term NORM exists also to distinguish ‘natural radioactive material’ from anthropogenic sources of radioactive material, such as those produced by nuclear power and used in nuclear medicine, where incidentally the radioactive properties of a material maybe what make it useful. European fertiliser manufacturing gave rise to discharges of phosphogypsum containing about 4 TBq/yr of Ra-226, Pb-210 and Po-210 into the North Sea and North Atlantic.

It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering and biological processes. Activity concentration guidelines for the use of NORM residues in building construction have been developed using the ACI approach and material has been classified into three categories, depending on whether the dose is below 0. ppm thorium, US coal-fired electricity generation in that year gave rise to 1100 tonnes of uranium and 2700 tonnes of thorium in coal ash.

Geological Survey, Fact Sheet FS-163-97, 1997 Radioactive Elements in Coal and Fly Ash: Abundance, Forms, and Environmental Significance. The production of REEs has been accompanied by the production of large volumes of thorium hydroxide and residues containing radioactive lead and radium. In China, coal-fired power plants are a major source of radioactivity released to the environment and thus contribute significantly to enhanced NORM there.
