Portable Under Vehicle Inspection

Portable Under Vehicle Inspection PUV-227

The PUV-227 is a well priced portable under vehicle inspection/search system. Despite the small size of this unit, many of the features and functionalities that are currently found in larger systems are available. Designed to be moveable and deployable on an “as-required” basis this unit solves many inspection problems.

The complete system with the aluminum ramp has been designed to easily pack into one, environmentally sealed Pelican™ case for easy transport. The PUV-227 is designed to be straddled by oncoming vehicles, but can withstand up to 40,000 lbs (18,143 kg) per axle if directly mounted.

The ramp housing contains two high-intensity, white LED, day/night cameras that fully capture the undercarriage of a passing vehicle, from wheel well to wheel well.

Inspections can be conducted from a distant location therefore dramatically increasing the safety of personnel. The PUV-227 is a full PC-based system with specialist software. The software features a dual-view inspection that functions with a standard touch pad that allows the user to access playback functions, such as pause, rewind, and fast-forward.

PUV-227 Designed for Ultimate Strength & Simplicity

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.
