NORM

What Does NORM Stand For?

NORM is an acronym for Naturally Occurring Radioactive Material. NORM exists in very low concentrations all around us because of radioactive elements found in the natural environment. NORM can be found in rocks and sand in the earth’s surface, and it travels to the earth’s surface due to natural processes. For example, radon gas moving through cracks in rocks or dissolving and being transported by ground water flows. Examples of these elements are uranium, thorium, potassium. The decay of these elements produces radioactive materials called isotopes like Radium-226 or Radon-222.  

Why is NORM Harmful?

The main concern with NORM is radiation. Some human activities that bring NORM to the surface may cause NORM to become more concentrated than its natural state. For example, coal ash from coal-burning power plants contains a more concentrated form of NORM than the coal did when it was taken from the ground. Because NORM is radioactive, once it is brought to the surface or concentrated, the ionizing radiation that it emits can now interact with humans.

How Does NORM Exposure Harm My Body?

The primary health risk of concern when dealing with NORM, is the potential for developing cancers, as the ionizing radiation that it emits is a known carcinogen. When exposure to ionizing radiation increases so does the risk of developing cancer. Cellular changes from ionizing radiation may also cause genetic damage or birth defects. Pregnant workers are also warned to minimize their exposure to NORM as radiation increases the risk of cancer to the growing fetus.
