Steel, Scrap Metal, Waste
to Energy, and Recycling
Recycling of re-usable resources conserves raw materials,
energy, and landfill space. Million of tons of iron and
steel scrap is recycled each year in the United States.
Steel making, foundry industries and virtually all
manufacturers that use recycled material rely on
radiation-free goods and components for their new
products. Recycled materials that are radioactively
contaminated threaten human health and the environment
while having a huge economic impact on the manufacturer.
This radioactivity can expose workers and ultimately be
incorporated into consumer products.
sources can escape from regulatory control by being
abandoned, lost, or stolen. Likewise, uncontrolled material
contaminated with natural or man-made isotopes from
industrial processes can also enter the recycling stream.
Two examples of this are pipe scale from oil and gas
drilling that contains naturally occurring radioactive
material and material improperly released from any nuclear
related industry that is contaminated with man-made radio
nuclides above regulated limits.
Since scrap metal
recycling is an increasingly international industry and as
the United States imports millions of tons of scrap metal,
semi finished metal, and metal products each year, it is
important to ensure that this metal is not contaminated with
radioactivity. There is always the possibility that more
highly contaminated materials could be exported to the
United States. LAURUS Systems is pleased to offer a full
range of detection and monitoring systems to help combat
this very serious environmental issue.
ISRI Safety and Environmental Council (lSEC) brings
industry leaders together twice a year to explore safety and
environmental issues, and to establish baselines for
acceptable performance. The council provides opportunities
to share ideas and to ask questions. It brings people
together to network and address challenges.
At the November, 2013 meeting in St. Louis, MO, Bonnie
Meilner, Regional Sales Manger for LAURUS Systems was
invited to make a presentation to industry professionals
addressing the challenges they face regarding radiation
monitoring, safety, and instrumentation when protecting both
personnel and assets. A downloadable version of this
presentation in PDF format is available here:
Radiation Safety and Equipment Considerations.
The entry level RC1000

The so-called “orphan
source” phenomena is a serious global problem; sources showing up
unexpectedly in scrap yards, border crossings, or numerous other
public locations are a significant potential threat. The RadEye
represents a high-performance measuring device for anyone
responsible for finding radiation sources; personnel
monitoring waste stream or specific areas within a facility,
interdiction teams (border guards, customs agents, special forces or counter
terrorism teams) or first responders (emergency services and law
