3. www.radecoinc.com For over 30 years, RADēCO is your “RAdiation Dētection COmpany” RADView TM PD Colorimetric Dosimeter “There have been plenty of efforts by terrorist smugglers to acquire these nuclear materials. According to the IAEA, between 1993 and 2004, there were 662 confirmed cases of smuggling nuclear and radiological materials, and those were just the cases that we know about. Of those confirmed cases, 21 involved materials that could be used to produce a nuclear weapon, and over 400 involved materials that could be used to make a dirty bomb. It is clear that this threat is very real and deserves our utmost attention.” U.S. Senator Jon Kyl, Chairman, Senate Judiciary Subcommittee on Terrorism, Technology and Homeland Security July 27, 2006

5. www.radecoinc.com For over 30 years, RADēCO is your “RAdiation Dētection COmpany” RADView TM PD Colorimetric Dosimeter The Need –The first known terrorist plot to attack the United States using a radiological dispersal device (RDD or “dirty bomb”) failed in 2002 when Jose Padilla was arrested. –The first attack on the World Trade Center (1993) also failed, but the second – September 11, 2001 – succeeded. –We know that Al Qaeda and other terrorist organizations are persistent and it is a widely held expert opinion that Al Qaeda will commit an RDD attack in the United States eventually.

6. www.radecoinc.com For over 30 years, RADēCO is your “RAdiation Dētection COmpany” RADView TM PD Colorimetric Dosimeter The Problem –Officials recognize that in the event of an RDD emergency, the initial response personnel may not be aware of the radiological nature of the attack. –First responders will need to carry dosimetry at all times in order to be truly prepared.

7. www.radecoinc.com For over 30 years, RADēCO is your “RAdiation Dētection COmpany” RADView TM PD Colorimetric Dosimeter The Options –For this application, thermoluminescent dosimeters (TLDs) will not be adequate because they cannot be read at the scene. –Pocket ionization chambers (PICs) are inexpensive, but require calibration and are notoriously subject to damage by shock. The readings are unreliable due to electrical charge drift and training is required to read them correctly. –Electronic dosimeters are high cost, relatively bulky for a person already carrying a significant amount of equipment, and require calibration and maintenance.

10. www.radecoinc.com For over 30 years, RADēCO is your “RAdiation Dētection COmpany” RADView TM PD Colorimetric Dosimeter How It Works –The RADView TM PD dosimeter badge incorporates a self-developing film which provides visual measurement of absorbed radiation dose. –The radiochromic film changes color upon exposure to ionizing radiation, becoming progressively darker in proportion to the absorbed dose. –The user simply matches the color of the sensitive film in the center of the display to the precalibrated comparison backgrounds to assess exposure. –If the sensitive film is darker than the background of a segment, the dose is greater than the number of that segment (“dose is darker”).

This indicates the badge has been exposed to a radiation dose between 5 rem and 10 rem. –In the third illustration, the dose is between 25 and 50 rem. Note that the center film is darker than the 25 rem segment and lighter than the 50 rem segment.

12. www.radecoinc.com For over 30 years, RADēCO is your “RAdiation Dētection COmpany” RADView TM PD Colorimetric Dosimeter Why It Works –Originally developed for the medical industry by International Specialty Products, the active component in the dosimeter is a microparticulate, radiation sensitive diacetylene monomer dispersed in a polymer matrix and applied to a polyester film base. –When the active monomer is exposed to ionizing radiation, a polymerization reaction immediately produces an intensely colored dye polymer that darkens the center of the display. –The amount of dye produces is proportional to the radiation dose received. –The dye polymer is cyan blue with a major absorbance peak at 635 nm and a minor peak at 585 nm.
