Course Description

PER-243, PER-245 and PER-246 - Preventative Radiological/Nuclear Detection On-Site (PRNDOS) Program

Last Verified/Updated 10/01/13


Course Description

Three classes, listed below, are being offered as a full-week training program:
1) PER-243, Personal Radiation Detector (PRD)
2) PER-246, Primary Screener/Backpack Basic (PS/BB)
3) PER-245, Secondary Screener/Radiation Isotope Identifier Device (SS/RIID)


These classes are offered for students who are in locations where CTOS cannot train a full complement of students due to not meeting the minimum class size or for jurisdictions who, through attrition, have lost personnel previously trained by CTOS. Students signing up for this program are required to attend the full suite of classes, if accepted.

Course Objectives
Note: Refer to the individual Course Descriptions of PER-243, PER-245, and PER-246 for more information.



Three courses comprise the PRNDOS program:




PRD Course (PER-2431) This one-day course focuses on the detection, alarm assessment, locating and mitigation of an event involving radiological/nuclear materials.
PS/BB Course (PER-2462) This course is designed to train law enforcement and public safety officers to employ department procured and issued backpack radiation detection systems within the bounds of the jurisdiction/agency operational environment, including local instruments, procedures, and legal considerations. The course provides training and extensive hands-on practice with actual radioactive material so that personnel employing a backpack radiation detection system during detection and interdiction missions can DETECT, VERIFY, LOCATE, MEASURE, and ACCESS potentially illicit radioactive material.
SS/RIID Course (PER-2453) This course is designed to train law enforcement officers, and personnel from other disciplines designated to support law enforcement agencies, to perform radiological/nuclear detection secondary screener duties, through the employment of radiation isotope identifier devices (RIIDs). The course provides training, which includes extensive hands-on practice utilizing actual radioactive material, to enable personnel assigned as secondary screeners to respond effectively to a request for assistance from a primary screener.

Radioactive Sources
This is a “live agent” course using radioactive materials. It is designed and monitored so participants receive only minor radiation doses (lower than a chest X-ray or typical round-trip airline flight across the U.S.).

This course complies with ANSI N42.37-2006, “American National Standard for Training Requirements for Homeland Security Purposes Using Radiation Detector Instrumentation for Interdiction and Prevention.”
