Apply comprehensive technologies and processes to achieve NORM decontamination

During hydrocarbon production, coprecipitation or electrochemical deposition of radioactive elements such as radium, polonium, and lead can generate potentially hazardous NORM.

Typically taking the form of barium or radium sulfate, elemental metallic lead, or other mineral scales, NORM deposits may pose HSE issues. Most of these deposits cannot be completely rectified with high-pressure water jetting or other conventional treatments.

DeScal descaling, decontamination, and decommissioning service teams have extensive experience in conducting successful NORM decontamination operations, using technologies and processes that minimize both HSE and economic risks.

Mobile units to reduce transportation risks

In addition to chemical solutions, the DeScal service team employs mobile decontamination units comprising tanks, cradles, pumps, and interlinking bunds. The mobility of these units allows onsite, point-of-generation decontamination, eliminating the risks involved in transporting hazardous radioactive equipment or waste.

Strict regulatory compliance

Irrespective of location, at a minimum every NORM decontamination project undertaken is managed under the auspices of UK IRR99 (Ionizing Radiations Regulations 1999) and in compliance with Radioactive Substances Act 1993 (RSA) standards.
