Sas R&D Services Inc. (SASRAD)

Originally formed in the United Kingdom in 1960 to manufacture and sell polycarbonate Riot Shields. Expanded into fields of IED (Improvised Explosive Devices) - EOD (Explosive Ordnance Disposal) - Mine Clearance - UXB (Unexploded Bombs) - Surveillance Equipment - Contraband Detection Equipment and training services.

Hunting Engineering PLC, acting as subcontractors to SASRAD manufactured the first Remotely Controlled Robot "HUNTER" designed by SASRAD, which was sold to 30 countries around the World including the USA. Rights to "HUNTER" were eventually sold to Hunting Engineering PLC in 1988 when SASRAD relocated its offices to the United States.

Since 1988 SASRAD has concentrated on hand held contraband detection equipment and over the years has become the World Leader in such equipment -the latest technology Density Meter (SAS-Hitech-Xpose)and first ever field repairable fiberscopes were introduced to the market to great acclaim followed by Videoscopes and other security equipment - all products are proudly manufactured in the USA.

SASRAD endeavors to respond to communications from its clients as speedily as possible and operates across all time zones to give best possible service.

The company relocated to the USA in 1988 due to the volume of US Government Business being conducted.

In 1992 the whole direction of the company was changed when we decided to concentrate on the field Of Contraband Detection and Search Equipment – we no longer work in any other field preferring to concentrate our efforts on the highly successful new technology equipment now offered by us.

Is a 7.5 microcurie radiation source safer than 10 microcuries as competitors claim?

This paper is intended to explain the difference in the Effective Dose to humans between 2 different activities (7.5 uCi and 10 uCi) of 133Ba isotope used in a hand held contraband detector relative to ordinary risk we face in everyday life.

A competitor of ours has offered a version of their unit which is 7.5 microcuries of radiation against our 10 microcuries, claiming that this is safer for the user, In fact, the increased dose to a user of a 10 uCi source over a 7.5 uCi source for a worst case scenario is essentially equal to what one gets in one second of airplane flight on a cross country trip from Washington, D.C. to Los Angeles, CA, a total flying time of up to five hours or 1 in 18,000

10 Microcurie Source

Now let’s compare both these radiation source activities and the actual working life of the source. The working life is based on the sources initial activity and the half-life of the isotope. For 133Ba, the half-life is 10.53 years. So for a 7.5 uCi source, the working life is about 35-40% less than the working life of a 10 uCi source. This translates that the dollar per dollar cost of the 7.5 uCi source is much higher than the cost of the 10 uCi source! And finally another consideration is the scanning time for the contraband detector. Excluding other factors involved, a 7.5 uCi source has 25% less photons/sec output than a 10 uCi source and this in turn increases the length of time it takes to complete a scan. This also may reduce the probability of positively identifying a concealed item (contraband)

The Xpose has graphing & digital display, available tablet remote control of all functions and is MIL STD 810G - Water Resistant to IP56 (waterproof available on request) - ISO9001:2008 and most importantly sold under an Exempt Radiation License from the NRC. In other words virtually no restrictions on sale, possession of transfer of the unit.

Our competitor has none of these features.

In short, when comparing the 2 activities (7.5 uCi and 10 uCi) 133Ba sources in hand held contraband detection systems: For those interested in the science and math behind these conclusions we do have a detailed white paper available upon request.

Radiation Licensing


There are several important points that users and potential users of the New Technology SAS-Hitech-Xpose Contraband Detector should be aware of. In order to simplify ownership of this device, SAS-Hitech-Xpose has been developed and licensed under United States Law as an Exempt device. Other density meters of this type are licensed under a General license. There are highly important differences between the two types of licenses. Here are a couple of the major differences:


General licensed (competitors product) requirements (per their own manual):
  • Rope or cordoning off the area to keep people away
  • Contact public health (radiological authorities) and emergency services provider for assistance
  • Notify the manufacturer
Exempt license requirements (SAS-Hitech-Xpose)

Pick up unit and send it to Authorized Service Center or factory for repair (nothing more)


General license (competitors) requirements:

The device is assigned to a specific location and cannot be assigned to another location without written notification to the radiation regulatory entity (State or Federal as applicable). If the device is given or transferred to another location, even if it is with the same agency (i.e. if PD Precinct 5 gives it to PD Precinct 6), a transfer of location must be filed by the user (licensee) prior to transfer. Failure to do so is subject to fine and reprimand.

Disposal of General Licensed unit: The user MUST dispose of the device as Hazardous waste and transfer to a license disposal facility. This can be done, under US law by:
  • Exporting the device in accordance with NRC regulations found in 10CFR§110
  • Transfer to a Specific Licensee authorized to receive the device with supporting documentation.
  • Transfer to another General Licensee under strict regulations found in 10CFR§31.5(c)(9) or equivalent Agreement State regulations.
Exempt license requirement (SAS-Hitech-Xpose)
  • Remove label and throw away in regular garbage.
Or for transfer of ownership
  • No restriction. It can be given it to whomever, whenever, wherever required. No paperwork/transfer licenses/authorizations required.
