On completion of this training course, you should have the knowledge to work safely in areas controlled for radiological purposes using proper radiological practices. Participants will demonstrate their knowledge by scoring >75% on a written examinat
ion and successfully complete a practical factors exercise.
Participants will demonstrate knowledge of the following by selecting from a group of responses.
From generic (Part 1) Topics:
From Site-Specific (Part 2) Topics:
- The definition of ionizing radiation, radioactive material, radioactive contamination, radioactivity, radioactive half-life, and ionization.
- The three basic particles of an atom.
- The four basic types of ionizing radiation, and the following characteristics for each type:
- Physical Characteristics
- Biological Hazard(s)
- The units used to measure radiation and radioactivity.
- Converting rem to millirem and millirem to rem.
- Distinguishing between ionizing radiation and non-ionizing radiation.
- The possible effects of radiation on cells.
- The mechanism by which radiation damages biological tissues.
- The definition of the terms acute dose, chronic dose, somatic effect,
and heritable effect.
- The range for various effects of acute radiation dose to include radiation sickness and death to 50% of the population exposed.
- The potential effects and relative risk associated with prenatal radiation doses.
- A comparison of the biological risks from chronic radiation doses to health risks workers are subjected to in industry and daily life.
- The average annual dose to the general population from natural background and man-made sources.
- The major sources of natural background and man-made radiation.
- The responsibilities of the Radiological Control Group.
- DOE dose limits and guidelines, including emergency exposure guidelines.
- Your responsibility to comply with DOE dose limits and Jefferson Lab administrative control levels.
- The action a worker should take if he or she suspects that dose limits or administrative control levels are being approached or exceeded.
- The DOE/Site management policy and the purpose of the ALARA program.
- The responsibilities of Management, Radiological Control Personnel and the Radiological Worker in the ALARA Program.
- The three basic protective principles of ALARA.
- Methods for reducing external and internal radiation exposure.
- Ways radioactive material can enter the body.
- How dose from internal radioactivity is determines.
- How external radiation dose is determined.

- Site-Specific dose reduction methods.
- The definitions of prompt radiation and activation.
- Major sources of prompt radiation and activation as well as ancillary radiation sources on site.
- The purpose of initial entry surveys.
- Requirements for removing material from the beam enclosure.
- The main types of engineered and administrative radiological controls, and thee elements of the Configuration Control program.
- The function of the access control system (Personnel Safety System) to include the status indicators and displays associated with the various modes.
- The purposes of and information found on Radiological Work Permits (RWPs) and your responsibility for the correct use of RWPs.
- The definitions of Controlled Area, Radioactive Materials Area, Radiation Area, and High Radiation Area.
- Requirements for entering, working in, and exiting the areas listed in 39.
- Radiological areas for which Level I radiological workers are prohibited, and the postings for each area.
- The purpose and use of personnel contamination monitors.
- The appropriate response to contamination monitor alarms.
- The purpose and types of emergency alarms or status indicators used at CEBAF and the correct responses in the event of an emergency or alarm.
- The possible consequences for disregarding radiological postings, instructions, alarms and/or status indicators.
