"If you know about radioactivity, you’re one step ahead"

A legislation that is becoming more restrictive alongside an ever growing environmental sensibility of implied agents, make that the radiological characterization of materials and the radiological control of non-nuclear industrials facilities are established as an indicative of a society truly compromised with the sustainable development.

For more than fifteen years, ENTEC Solutions team has worked on the research and development of natural radiation and environment. The quality of development measurement methods and techniques, as well as the importance of results obtained through the application of the aforementioned methods and techniques are thoroughly supported by being issued in scientific magazines and international standing conferences.

  • Projects on the framework for the Basic Safety Standards (BSS) Directive, relative to the determination of Radon in workplaces, the radiological evaluations of industrial complexes, and the evaluation of areas affected by NORM activities (MARSSIM methodology applications).
  • Radiological characterization of wastes.
  • Determination of radionuclides concentration in environmental and industrial samples, as well as samples suitable for human consumption (water, soil, vegetables, food, etc).


The International Atomic Energy Agency (IAEA) defines NORM (acronym for Naturally Occurring Radioactive Material) as all material with a radioactivity of a natural origin, but which potential has been increased by some kind of human activity, compared with an unchanged state.

In this sense, it can be defined as NORM industries those non-nuclear industries which either process raw materials with high concentration of natural radionuclides, or bring about, through its activity, the concentration of those radionuclides in some of its products or wastes. As a consequence, there can be an increase of exposition to ionizing radiation in workers, and consequently in member of the public, although in some cases, it may not be as insignificant, from the point of view of radiological protection.

Non-exhaustive list of the activities whose responsible must carry out the regulated studies for the BSS, detailed in the following:
  • Underground work places, such as:
    • Caves and galleries.
    • Mines different from uranium ones.
  • Thermal establishments.
  • Facilities for the storage and treatment of underground water.
  • Work sites, underground and non-underground, in areas identified by high levels of Radon.
  • Extraction of rare earth elements.
  • Production and use of Thorium and its compounds.
  • Production of niobium and iron niobium.
  • Production of gas and oil.
  • Production of cement, maintenance of clinker furnaces.
  • Manufacturing of titanium dioxide pigments.
  • Zirconium industry.
  • Phosphate industry
  • Production of tin, copper, aluminum, iron, steel, zinc and lead.
  • Coal-fired thermal power station.

We are specialized in Low Level Counting (determination of low radioactivity concentrations) Applied in the determination of radionuclides in the environment: water, soil, atmosphere and biota, relying on advanced procedures and tools.
