    Policy Summary

    This policy describes Berkeley Lab's requirements for the monitoring of individuals and workspaces for radiation exposure levels, contamination, and airborne radioactivity.

    Who Should Read This Policy

    All persons who plan to work in or near an area controlled for radiological protection or who plan to work with or support work with radiation-generating devices or radiological materials

    POLICY

    A. Purpose

    This policy describes Berkeley Lab's requirements for the monitoring of individuals and workspaces for radiation exposure levels, contamination, and airborne radioactivity.

    B. Persons Affected

    All persons who plan to work in or near an area controlled for radiological protection or who plan to work with or support work with radiation-generating devices or radiological materials

    C. Exceptions

    None

    D. Policy Statement

    D.1 Personnel Monitoring

    1. External Dosimetry:Berkeley Lab's external dosimetry program is managed by the Radiation Protection Group (RPG). Elements of the program include, but are not limited to, the following:
      1. Radiation workers exposed to external ionizing radiation will be issued a dosimeter as required by their work authorization.
      2. RPG provides extremity dosimeters for personnel who have the potential to receive an extremity dose that is significantly higher than the whole-body dose.
      3. RPG provides electronic personnel dosimeters (EPDs)
    2. Internal Dosimetry
      1. Berkeley Lab's internal dosimetry program is managed by the RPG and includes:
      2. In vitro (body fluid) monitoring
      3. In vivo (whole-body counting) analysis

    D.2 Workplace Monitoring

    1. General: Workplace monitoring provides a basis for posting and labeling of areas and equipment, developing work authorizations, implementing as low as reasonably achievable (ALARA) measures, issuing individual monitoring devices, and verifying the efficacy of design measures and engineering controls.
    2. Passive Area Dosimetry: To demonstrate that the doses outside Radiologically Controlled Areas are negligible, the RPG has established and maintains a comprehensive area dosimetry program (passive dosimeters). The measurements provide information that supports radiological safety decisions, particularly with regard to personnel doses and the requirement to monitor individual personnel doses.
    3. Active Area Monitoring: To demonstrate that the doses outside Radiologically Controlled Areas are negligible, the RPG has established and maintains a comprehensive area monitoring program (telemetered instruments). The measurement results provide information that supports radiological safety decisions, particularly with regard to personnel doses and the requirement to monitor individual personnel doses.
    4. Surveys:Routine and periodic radiation and/or contamination surveys look for changes in conditions, ensure that controls are adequate, decommission areas, or release equipment and materials. These surveys are performed by:
      1. Radiation workers (users)
      2. RPG staff
      3. Specifically trained and authorized personnel
    5. Air Monitoring: Based on an RPG assessment of the operation and in accordance with RPG procedures, air sampling will be performed within areas where there is the potential for airborne radioactive contamination.

    D.3 Instrumentation

    RPG provides radiation workers with appropriate, calibrated radiation-detection equipment. The RPG provides guidance in the selection of instruments, in addition to instrument distribution, calibration, and maintenance.

    E. Roles and Responsibilities

    Role

    Responsibility

    Radiation Protection Group (RPG)

    • Provides appropriate external dosimetry to radiation workers
    • Implements internal dosimetry measures, as required
    • Assesses areas and operations for the potential of airborne radioactive contamination; establishes appropriate sampling
    • Maintains and provides instrumentation to the radiation workers
    • Establishes and maintains the passive area dosimetry program
    • Establishes and maintains the active area monitoring program
    • Performs routine and periodic radiation and contamination surveys

    Radiation worker

    • As authorized, performs routine and periodic radiation and contamination surveys
    • Acquires external dosimetry, as required by the work authorization
    • Participates in the internal dosimetry program, as required by the work authorization

    Supervisor/manager

    Verifies radiation workers have external dosimetry and participate in the internal dosimetry program, as required by the work authorization

    F. Definitions/Acronyms

    Term

    Definition

    External dosimetry

    Methods for measuring amount of energy deposited in body tissues from external sources

    Internal dosimetry

    Methods for measuring amount of energy deposited in body tissues from internal sources

    As low as reasonably achievable (ALARA)

    ALARA describes an approach to radiological management and control that aims to keep exposures (individual and collective) of the workforce and of the general public at levels as low as is reasonable, taking into account social, technical, economic, practical, and public-policy considerations.

    Radiological Area

    Any area within a Radiologically Controlled Area that must be posted as a Radiation Area, High Radiation Area, Very High Radiation Area, Contamination Area, High Contamination Area, or Airborne Radioactivity Area

    Radiologically Controlled Area

    Any area to which access is managed to protect individuals from exposure to radiation or radioactive materials. Individuals who enter Controlled Areas without entering Radiological Areas are not expected to receive a total effective dose equivalent of more than 0.1 rem (0.001 sievert) in a year.

    Work authorization

    An authorization for the use of radiation-producing machines and/or radioactive materials. Precautions, limits of use, and requirements are specified.

    G. Recordkeeping Requirements

    The care, maintenance, and disposition of RPG records will be done in accordance with Berkeley Lab records management policies and procedures, as listed in the Requirements and Policies Manual (PUB-201).
