OVERWATCH I offers some truly unique services, and has participated in projects that the public rarely hears about. Some of the most interesting examples would be the following:

 

- Radiation detection support for robotic investigation of suspicious packages, such as a "dirty bomb".
 

 
- Inspection of lead walls around x-ray and nuclear medicine installations, both new and renovated. Customers include Parkin Architects Ltd of Toronto and Ellis Don Construction.
- Provision of cooperative nuclear training services with such high profile companies as Vanguard Response Systems Inc. See the news releases below:

Below are a few interesting investigations we've heard of or been involved with.  Check back again; we'll be adding to it regularly.

Number 1. SAIC-Exploranium GR-606 Waste Monitors

This gamma radiation detector uses a large plastic scintillator crystal as a primary detector. It includes lights and a sound alert as well as a remote annunciator that can be located some distance from the detector. It functions extremely well as a corridor mounted waste monitor that will alarm when radioactive hospital waste is pushed by it en route to the compactor or dumpster. This system will greatly reduce the risk of having your waste hauler return radioactive waste to you, with the accompanying costs.

Next, an x-ray scan of a truck...

and, yes, those are stowaways in there.

Third, an abandoned 241-Am/Beryllium neutron source, as seen in the following picture...

The following is the NaI spectrum from the above sample, read on a GR-135 Identifier. Since the GR-135 was equipped with a neutron detector it also alarmed.

 

Number 4. An unknown source, circular, about 1" diameter. This is Ra-226, but what was it used for? For details of yet another unidentified sample, click here.

Number 5. Radioactive chewing gum caught at a US border crossing and extracted from 33 tons of garbage...

Number 6. One of two pair of new SAIC-Exploranium GR-510 radiation detector systems located at W-M Philadelphia Transfer Station. Mr. Butch Walton, the District Manager, participated in the GR-135 Identifier training given by Overwatch.

Number 7. This is "The Forge" Transfer Station with one of its pair of GR-510 radiation detector systems. Mr. Wallace Benson is the manager who participated in the GR-135 Identifier training program.
