KI4U Radiation Lab Tested & Recently Calibrated
KI4U, Inc. is licensed and authorized by the State of Texas
(Bureau of Radiation Control License No. L05515). KI4U is the only
private, non-government, lab that specializes in calibrating high-range Civil
Defense instruments. This Survey Meter has been rigorously inspected,
tested and calibrated at the licensed radiation calibration
laboratory - KI4U. It is fully ready for reliable, accurate and
confident service in the field.
These units are taken through preventative maintenance, tests and
evaluations prior to calibration. After passing the KI4U lab calibration they
are then certified and a calibration sticker is placed on the unit showing the
calibration date and other relevant information.
Radiation meters SAVE LIVES. ONLY HIGH LEVELS of radiation
are fatal. It takes 300 to 500 Rads of Total Dose for 50% of those
exposed to die.
The CD V-717 is a modification of the CD V-715 ionization chamber
survey meter. Its operating
characteristics and specifications are very similar to those of the CD V-715,
except that the 717 has a removable hermetically sealed chamber that can be
attached to 25 feet of cable. This gives the 717 the ability to make remote
readings, e.g., with the chamber outside the monitoring station where it is
used. The CD V-717 portable
monitoring instrument measures gamma radiation dose rates as high as 500
roentgens per hour (R/hr). It is
designed to be used in determining radioactive contamination levels that may
result from an enemy attack or other nuclear disaster. The CD V-717 consists of three case
sections. The top section contains the meter
and almost all of the circuitry. The
bottom section contains the ion chamber and provides for storage of the 25 feet
of cable and the storage spool. The
center section provides for electrically connecting the circuit board on the
top section to the chamber from the bottom section. The case sections are electrically connected
through two triaxial connectors which mate when the case sections are locked
together. The instrument may be operated
as a handheld portable type survey instrument when all case sections are locked
together, or, the bottom section of the case may be removed and the 25 foot
triaxial cable employed to allow remote sensing operation of the ion chamber
detector. It has had two controls: a
zero adjust knob and a range switch. The range selector switch which
turns the instrument on checks its operation and serves to select the proper
range. The zero control is used to
adjust the supply voltage to compensate for battery aging, temperature
variations, thus, insuring rated accuracy for any reading taken
The purpose of this instrument is explained in the following quote
from CPG 1-30 (FEMA 1981): "This instrument was designed for use by
radiological monitors in WER stations during the early period following a
nuclear attack. The purpose of the instrument is to decrease the radiation
exposure to monitors by making it unnecessary for the monitor to leave his
shelter in order to obtain an outside measurement."
The term "WER" refers to the Weapons Effects Reporting
stations which had previously been referred to as Fallout Monitoring or Fixed
Monitoring stations. According to CPG 1-30, they are facilities with fallout
protection, reliable communications, instruments and trained monitors that are
designated for the collection and reporting of weapons effects and radiological
data to the local Emergency Operating Center (EOC).
- Weighs 5.23 pounds, die cast
aluminum and drawn steel case, watertight, will float.
- Powered with one D-sized battery will
operate continuously for 150 hours, longer if on intermittent basis.
- Instrument accuracy on any of its
four ranges is within +- 20% of true dose rate.
- Accuracy maintained throughout
temperature ranges of -20 F to +125 F, relative humidity to 100% and
altitudes up to 25,000.
- Scales/Range: X0.1: 0 - 0.5 R/hr, X1: 0 - 5.0 R/hr, X10:
0 - 50 R/hr, X100: 0 - 500 R/h.
- Response time:
95% of final reading in nine seconds, two minute warm up.
- Use of the remote cable feature
should give less than +- 5% change in reading.
- These units may look
slightly used cosmetically.
*** IMPORTANT - How this
Meter Reads Radiation ***
This meter is NOT for measuring
common, normal, background radiation, NOT for
measuring radiation that might be in food or water, or very small radioactive
particles that might be on your clothing or skin. For that get the CD V-700
GEIGER Counter Radiation meter, it will measure that low, but it won't measure
radiation any higher than 50 miliRads/hour.
This meter MEASURES how
MUCH radiation you are getting PER
HOUR. It does NOT measure your
TOTAL Accumulated DOSE. FOR DOSE monitoring you want something as
simple as a RADSTICKER or a CDV-742 DOSIMETER and CDV-750 charger.
You may find CD V-717's on EBay or other such sites but they are
almost always surplus items that have not been inspected, tested, repaired or
calibrated. Just because it's advertised as working doesn't unnecessarily mean it's been calibrated.
These instruments require periodic calibration to function
an uncalibrated device could expose you to dangerous levels of radiation.
Calibration can only be performed by a licensed radiation calibration lab such
Don't wait until a nuclear crisis occurs to order one of
these. Once a crisis occurs the demand will almost certainly outpace the
