Subject Matter Expertise coupled with extensive and demonstrable in-field capability is why Radiation Professionals’ bring assurance of safety, confidence and control.  In the hands of the Professionals.

Optimisation of industrial process environments increases asset availability and performance.  The unique challenges faced by process intensive oil, LNG, mining and metals processing demand Informed and competent management of hazardous materials and their related risks.

There are three major components that figure into radiation dose: time, distance, and shielding:

  • Time: The less time you spend exposed to radiation the lower your dose. During operations ensure that you have a clear knowledge of what radionuclides are present and the mitigations to limit dose.
  • Distance: Like most other physical phenomena, radiation decreases with distance in accordance with the inverse square law. [/su_list]

This means that the further away you are from the source of the radiation, the less radiation you’ll be exposed to. Workflow design should consider that you, and anyone else around, are active as far away from the radiation source as practicable.

  • Shielding: As ionizing radiation passes through matter; the intensity of the radiation is diminished. Thus, to protect yourself from radiation you should consider a barrier or shield. [/su_list]

However, the material you use matters significantly; some materials reduce the intensity of radiation more than others. Every material has a “halving thickness.” This is the thickness required to reduce the radiation intensity by half. So, if the halving thickness of a material is 1 inch, then a 1-inch-thick sheet will cut the radiation to 50%. Two inches will cut the radiation to 25%, 3 inches to 12.5%, and so forth.
