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.

Radiation Safety and Equipment Considerations.
The entry level RC1000
series of radiation detection systems have been designed for lower
density materials such as waste and light/bulky scrap metal. The
vehicle size and type will help determine the appropriate detector
panel size (34L or 69L). The RC1000 detection systems all utilize
RadComm’s high quality specially prepare Polyvinyl Toluene (PVT)
scintillators. The proprietary PVT design has been optimized to
allow maximum light output during scintillation events. The RC1000

arrangement with high gain, low noise, photo multiplier tubes (PMT’s)
and infrared vehicle presence sensors that enable the system to
better focus on the specific background radiation levels as the
vehicle travels between the detector panels.
The RC4000 Series of radiation detection systems have
been specifically designed to detect radioactive materials

kind in the world and has been proven to withstand the harsh
environment of a scrap handling operation - regardless of the
material being handled.

The RC2 Plus is a reliable and rugged handheld radiation
detector with “Search and Find” capability. It has been designed to detect very low radiation intensity levels from
radioactive materials. The RC2 is an extremely
effective handheld detector that utilizes a large 32 cu.in. (0.54L)
internal PVT plastic scintillation detector, a common material found
in most larger vehicle monitoring systems.
The RC2 Plus Advanced is an upgrade option from
the RC2 Plus Basic Total-Count version. The Basic version
tracks the total count rate produced by all of gamma energies
during the scanning period and automatically sets an alarm
threshold over the background count rate average. The Advanced
ROI Analyses versions allows the operator to see the
distributed of measured radiation energies in a histogram
where specific Regions Of Interest (R.O.I.) can be selected
for desired energy ranges applicable to the requirement.
