The RADView™ PD dosimeter badge is a credit card size radiation
dosimeter incorporating a self-developing radiochromic film to
provide visual measurement of absorbed radiation dose. The film
develops a distinctive and characteristic color upon exposure to
ionizing radiation, becoming progressively darker in proportion
to absorbed dose. RADView™ PD dosimeters are unaffected by brief
exposures to sunlight or normal room light. The films are water
resistant, tissue equivalent, energy independent and dose-rate
independent. The badges do not require calibration or
maintenance, have no electronics or batteries, and are small and
light. The RADView™ PD can be read visually by the wearer at the
incident scene. Accuracy is within 5% and combined accuracy and
precision is within 10% in voluntary testing performed with a
NAVLAP calibration facility %. The visual readout does not
require darkroom or processing equipment.
Under most conditions, the dosimeter can be worn for one year
before replacement. A quick visual observation of a RADView™ PD
dosimeter allows anyone to assess the absorbed dose. Once an
exposure is visually evident, a fully quantitative measurement
to confirm the radiation dose can be performed, if required, by
optically scanning the RADView™ PD dosimeter. An independent
readout and evaluation source can be provided
.

In the RADView™ PD dosimeter, annular segments with
calibrated background colors surround the radiation sensitive
film in the center of the graphic display. The color of each
segment is calibrated to the dose printed on that segment. The
background colors of each segment are permanently printed on the
badge and do not change, providing a constant reference value
for each dose level. If the sensitive film in the center is
darker than the background of a segment, the dose is greater
than the number on that segment (“dose is darker”), as shown in
the examples below.
NOTE: Action guidance and annular segments are based
on USEPA Emergency Response Worker Guidelines (see below)

Dosimeters can be prepared with the wearer’s
name and affiliation printed on the badge. Quantity discounts
are available for military and first responder organizations
under a subscription plan that sends new dosimeters before the
expiration date. RADeCO, a veteran-owned small business, is the
exclusive worldwide distributor for RADView™ PD dosimeters.
Laboratory readouts and dose evaluations can be provided by Dade
Moeller & Associates, Inc. under an exclusive agreement with
RADeCO.
