If transport of ore, processed concentrates or generated residues from mining of Uranium, Rare Earths or any further commodity containing Naturally Occurring Radioactive Material (NORM) is needed, the strict class 7 requirements apply. These IAEA transport requirements ensure comprehensive safety for the...
Uranium is a naturally occurring radioactive element, which has the atomic number of 92 and corresponds to the chemical symbol U in the periodic table. It belongs to a special group of elements called “actinides” — elements that were discovered relatively late in history. Like all other act...
Sixteen oil and gas facilities in Pakistan were characterised for evaluation of Naturally Occurring Radioactive Material (NORM). This first-of-its-kind study may determine the need to establish national regulatory requirements for NORM activities. Gamma dose rates at each site and specific activities ...

Abstract: Naturally Occurring Radioactive Materials (NORM) in Scales Formed During the Production of Oil and GasJohn E. OddoHouston Geological Society Bulletin
Naturally Occurring Radioactive Materials (NORM) The second type, diffuse NORM, has a much lower concentration of radioactivity, but a high volume of waste. This type of waste poses a different type of disposal problem because of its high volume. The following are six sources of such naturally...
