CHAPTER 1
INTRODUCTION
Section I. GENERAL INFORMATION
a. This manual describes Radiacmeters IM-9E/PD, IM-93/UD and
IM-147/PD. It guides you, the operator, as you operate and maintain this
equipment.
b. Throughout this manual, Radiacmeters IM-9E/PD, IM-93/UD, and
IM-147/PD are also called dosimeters. Don’t be confused by these terms,
a dosimeter is a radiacmeter.
c. The IM-93/UD and IM-147/PD Radiacmeters are used to detect and
measure large-scale radiation, e.g., a nuclear contaminated area. The
IM-9E/PD Radiacmeter is used to detect and measure small-scale radiation,
e.g., a laboratory environment.

1-4. DESTRUCTION OF ARMY ELECTRONIC MATERIEL TO PREVENT ENEMY
USE
Evacuation, rather than destruction, is first priority, whenever possible. Destruction,
when necessary, will be accomplished only upon the order of the
Commander.
Each using organization and/or installation having custody of radiacmeters
should have a Standard operating procedure (SOP) for radiacmeter destruction.
This demolition plan should be suitably flexible to cover any situation.
Destruction method should consider troop availability, materials required,
time needed, etc. Some of the methods used for destruction are smashing,
exploding, and burning (with manual) after demolition.

your clothing (shirt
pocket is ideal).
or
● attach your dosimeter
to any object (tree,
tent, rock, etc.) in
the area you wish to
check.
2-5. READING YOUR DOSIMETER
NOTE
Always hold dosimeter level to ground. If
you lie down, tilt your head to read the
dosimeter, or hold the dosimeter at an
angle, you’ll get inaccurate readings.
2-13

2-5. READING YOUR DOSIMETER - Continued
● look towards a light
source through the
eyepiece lens of the
dosimeter.
2-14

2-5. READING YOUR DOSIMETER - Continued
● rotate the dosimeter until the calibrated scale is horizontal.
NOTE
Always hold dosimeter level to ground. If you lie down, tilt your
head to read the dosimeter, or hold the dosimeter at an angle,
you’ll get inaccurate readings.
2-15

● note the position of the shadow
(hairline) on the calibrated
(reticle) scale.
● determine the amount of radiation
detected.
2-6. DETERMINING THE RADIATION DOSAGE
To figure out how much radiation you were exposed to, just subtract your
initial reading (taken before you use the dosimeter) from your final reading
(taken after a certain exposure time, i.e., month, day, hour, etc.).
2-16

234-544 - 89 - 2
2-6. DETERMINING THE RADIATION DOSAGE - Continued
NOTE
In some instances, you will have to estimate your readings, as in
the previous example where the shadow (hairline) fell between
two markings. Since each marking equals 20 RADs, the values
between the 100 RAD mark and the first mark following has a
range from 101 to 119. Because the shadow falls approximately in
the middle, the value is about 110 RADs.

2-7. ADMINISTRATIVE STORAGE
a. Check TM 740-90-1 for general information about the requirements
and procedures for administrative storage.
b. Although this general information does apply to dosimeters, you must
also follow some additional procedures for proper storage of dosimeters.
Before storing, charge dosimeters to zero. After removing from storage,
check to see that the dosimeters are fully charged at zero; if not, charge to
zero.
c. Before the dosimeter is placed into administrative storage (1 to 45
days), it should be cleaned, charged, and packed in a paperboard carton.
Place the packaged dosimeter in a sheltered area away from any known
radiation source.
2-8. PACKAGING-PACKING REQUIREMENTS

MAINTENANCE INSTRUCTIONS
Section I. TROUBLESHOOTING
This manual does not list all possible malfunctions that may occur, or all
tests or inspections, and corrective actions. If a malfunction is not listed,
notify your supervisor.
Malfunction, Test or Inspection, Corrective Action
Leakage rate exceeds acceptable values (para 1-6b).
Check electrical leakage rate, recharge, and clean.
If the leakage rate exceeds the acceptable standards, clean the
charging end of the dosimeter. Recheck the leakage rate. If the
leakage is still higher than the values in paragraph 1-6b, the dosimeter is
defective and should be turned in for a replacement. Perform leakage
test according to steps in paragraph 3-2.
Change 1 3-1

Section II. MAINTENANCE PROCEDURES
3-1. INTRODUCTION
Maintenance on your dosimeter consists of cleaning, decontaminating, testing,
and troubleshooting. You will extend the useful life of your dosimeter
by carefully following these procedures.
3-2. LEAKAGE TEST
Your dosimeter’s charge will gradually leak off, even though the dosimeter
is not exposed to X- or gamma-rays. This leakage, if excessive, will cause an
improper reading on the dosimeter.
3-2
NOTE
If your dosimeter has not been charged for more than one month
(or has been stored uncharged) or for an unknown length of time
and is then fully charged, excessive leakage may occur due to
INSULATION SOAK-IN (penetration of part of the charge into
the insulation). Do not perform a leakage rate check on the dosimeter
until it has been charged-to-zero each day for five consecutive
days. Ignore the daily leakage.

3-2. LEAKAGE TEST - Continued
The leakage rate should not exceed 2% of full-scale reading per day (see para
1-6b for maximum acceptable leakage specs). Check the leakage rate as
follows:
a. Charge the dosimeter using Radiacmeter Charger PP-1578A/PD to read
0 on the calibrated scale.
b. Store the dosimeter in a radiation-free area for a 24-hour period.
c. Note the reading on the calibrated scale of the dosimeter. This reading
represents the leakage rate in either RADS/ROENTGENS or millirads/
milliroentgens per day.
NOTE
If one day’s leakage rate is difficult to determine, the charged
dosimeter may be allowed to sit for several days until a readable
value is obtained. To determine the average daily leakage rate,
divide this value by the number of days the charged dosimeter sat.
Change 1 3-3

3-2. LEAKAGE TEST - Continued
d. If the leakage rate exceeds the maximum acceptable rate (para l-6b),
clean the charging end of the dosimeter.
e. Recheck the leakage rate. If it is still greater than the values in paragraph 1-6b,
the dosimeter is defective and must be turned in for a replacement.
3-3. REPAIR
There is no repair authorized at operator level. If your radiacmeter is defective,
refer it to your unit commander for possible evacuation to higher level
of maintenance.
3-4. CLEANING AND DECONTAMINATING
a. Materials required
The following materials are required for maintenance of the dosimeter:
(1) Denatured alcohol (NSN 6810-00-201-0906)
or
isopropyl alcohol (NSN 6810-00-753-4993).
