031-503-2023 (SL2) - Measure Radiation Dose Rate and Total Dose

Standards: Performed operator preventive maintenance checks and services (PMCS) on equipment used. Reported and recorded accurate readings (+ 5 centigray [cGy]) to supervisor. Complied with the commander's operation exposure guidance and turn-back dose rate without overexposing personnel.

Conditions: Given a tactical situation where nuclear contamination has occurred and radiation monitoring has been directed in your unit area. You are provided with an individual team or squad; radiation, detection, indication, and computation (RADIAC) detection equipment (dosimeters must be of the same type); a nuclear, biological, and chemical (NBC) marking set; a watch; (a vehicle or an aircraft, depending on mission requirements); communications equipment; DA Form 2404, Equipment Inspection and Maintenance Worksheet, 1971-R, Radiological Data Sheet-Monitoring or Point Technique, and DA Form 1971-6-R, Chemical/Biological Sample Documentation; and with applicable technical manuals (TMs), technical bulletins (TBs), and standing operating procedures (SOPs). Given the supervisor's guidance on continuous or periodic monitoring, the use of direct or indirect technique, intervals between readings (for monitoring dose rates only), and communication and reporting procedures.

Standards: Performed operator preventive maintenance checks and services (PMCS) on equipment used. Reported and recorded accurate readings (+ 5 centigray [cGy]) to supervisor. Complied with the commander's operation exposure guidance and turn-back dose rate without overexposing personnel.
Note. There is no degradation to standards if this task is performed in MOPP 4.

Performance Steps

1.   Perform PMCS on the RADIAC equipment.

a. Use TM 11-6665-232-12 for PMCS on the IM174 series RADIAC meter.

b. Use TM 11-6665-251-10 for PMCS on the AN/VDR-2 RADIAC set.

c. Use TM 11-6665-365-12&P for PMCS on the AN/UDR-13 RADIAC set.

d. Use TM 11-6665-214-10 for PMCS on the IM93 dosimeter.

e. Use TB Signal (Sig) 226-8 for PMCS the PP1578 RADIAC charger.

f.  Use TM 11-6665-236-12 for PMCS on the AN/PDR-75 with DT-236 dosimeter.

2.   Measure the radiation dose rate.

a. Use TM 11-6665-232-12 for operation of the IM174-series RADIAC meter.

b. Use TM 11-6665-251-10 for operation of the AN/VDR-2 RADIAC meter.

c. Use TM 11-6665-365-12&P for operation of the AN/UDR-13 RADIAC meter.

d. Record the data on DA Form 1971-R.

e. Report the data to the supervisor.

Note.  The data will be placed into an NBC 4 nuclear report by your supervisor or the unit NBC control party.

f.  Conduct continuous or periodic monitoring (guidance received from supervisor).

g. Use the direct or indirect technique (guidance received from supervisor).

h. Take readings at proper intervals (guidance received from supervisor).

3.   Measure the total dose of radiation.

a. Use TM 11-6665-251-10 to measure the total dose with the AN/VDR-2 RADIAC set.

b. Use TM 11-6665-214-10 to measure the total dose with the IM93 dosimeter.

Note.  The DT-236 is worn on the wrist like a wristwatch, and measures cumulative doses of gamma and neutron radiation.  It augments the IM93.  The company AN/PDR-75 operator reads the DT-236.  The company NBC control party records and processes this data.

c. Use TM 11-6665-365-12&P to measure the total dose using the AN/UDR-13 RADIAC set.

4.   Record the data on DA Form 1971-R (except for DT-236).

5.   Report the data to supervisor (except for DT-236).

Evaluation Preparation:

Setup: Evaluate this task during a field exercise or a tactical training session. The AN/TDQ-T1 large-area RADIAC training set can be used to produce readings for RADIAC meters and RADIAC sets.

Brief Soldier: Tell the soldier that the test will consist of performing PMCS, preparing the equipment for use, monitoring a designated area, recording the total dose/dose rate, and reporting the results to the supervisor. The actual completion of DA Form 2404 and DA Form 1971-R is not degraded if this task is performed in MOPP 4.
