50.1 Policy

Berkeley Lab has an established and implemented program to protect the public and the environment against undue risk from radiation associated with radiological activities. This program is tailored to Berkeley Lab activities and uses a graded approach. The program ensures compliance with public dose limits and ensures that potential radiation exposure to the public and environment from Berkeley Lab activities is as low as reasonably achievable (ALARA).

50.2 Scope

 This policy applies to:

50.3 Applicability

Berkeley Lab managers, supervisors, employees, and affiliates who plan to work with or support work with radiation-generating equipment or radioactive materials

50.4 Exceptions

None

50.5 Roles and Responsibilities

Responsibilities

Principal Investigators and Supervisors

  • Ensure that environmental laws, regulations, and policies are followed
  • Request technical advice from the Environmental Services Group on what environmental requirements apply to their operations and what compliance strategies are appropriate
  • Ensure that activities are performed within acceptable operating standards and that any required records are current
  • Notify the Environment, Health, Safety, and Security (EHSS) Division immediately of any unplanned releases

Employees

  • Follow applicable environmental laws, regulations, and policies
  • Must be fully aware of the environmental impact of their activities, and comply with all requirements that govern those activities
  • Perform activities within acceptable operating standards, and maintain current records whenever required
  • Ensure that exposures of the public and the environment to radioactive emissions and discharges are kept as low as reasonably achievable (ALARA)
  • Take immediate action to stop unplanned releases to the environment, and report all instances of unplanned environmental releases to the EHSS Division
  • Complete all required training provided by supervisors and the EHSS Division

Environmental Services Group

  • Develops Laboratory policies and procedures to assure that operations are conducted in an environmentally safe manner and in full compliance with all applicable environmental laws and regulations and Department of Energy (DOE) orders
  • Prepares environmental compliance plans and reports as mandated by DOE orders and Environmental Protection Agency (EPA) requirements
  • Assesses current and planned Berkeley Lab programs, and assists in defining environmental-protection compliance upgrades and corrective actions
  • Identifies significant institutional environmental-compliance issues, and develops cost-effectivemechanisms for resolving them
  • Performs environmental dose assessments to document that radiation doses to the public and environment are maintained well below the applicable standards and regulations
  • Prepares budget requests for and manages environmental-protection upgrades and corrective actions for institutional projects
  • Curtails or suspends any operations that pose an immediatedanger to members of the public or the environment
  • Monitors radioactive emissions and discharges to the environment to verify compliance with applicable regulations
  • Investigates reports of unplanned environmental releases, and notifies appropriate authorities in a timely manner, asrequired
  • Coordinates and represents Berkeley Lab activities during environmental audits and inspections by regulatory agencies and DOE
  • Responds to information requests from the public

50.6 Definitions

Term

Definition

As low as reasonably achievable (ALARA)

“An approach to radiation protection to manage and control releases of radioactive material to the environment and exposure to the work force and to members of the public so that the levels are as low as is reasonably achievable, taking into account societal, environmental, technical, economic, and public policy considerations; ALARA is not a specific release or dose limit but a process that has the goal of optimizing control and managing releases of radioactive material to the environment and doses so that they are as far below applicable limits as reasonably achievable” (from DOE O 458.1)

Collective dose

“The sum of the total effective dose to all persons in a specified population received in a specified period of time; collective dose is expressed in units of person-rem (or person-sievert)” (from DOE O 458.1)

Effluent

Any treated or untreated liquid discharge from Berkeley Lab or from a Laboratory facility

Emission

Any filtered or unfiltered substance released to the air from Berkeley Lab or from a Laboratory facility

Environmental surveillance

“The collection and analysis of samples of liquid and gaseous effluents or measurements of liquid and gaseous effluents performed to characterize and quantify radiological contaminants and process stream characteristics, assess exposures of members of the public, and demonstrate compliance with applicable standards” (from DOE O 458.1)

Equivalent dose

“The product of average absorbed dose in rad (or gray) in a tissue or organ and a radiation weighting factor. For external dose, the equivalent dose to the whole body is assessed at a depth of 1 cm in tissue, the equivalent dose to the lens of the eye is assessed at a depth of 0.3 cm in tissue; and the equivalent dose to the extremity and skin is assessed at a depth of 0.007 cm in tissue; equivalent dose is expressed in units of rem (or sievert)” (from DOE O 458.1)

Radionuclide

A natural or man-made atom that spontaneously undergoes radioactive decay

Technologically enhanced naturally occurring radioactive material (TENORM)

“Any naturally occurring radioactive material whose radionuclide concentrations or potential for human exposure has been increased above levels encountered in the natural state by human activities” (from DOE O 458.1)

Total effective dose

Sum of doses from external and internal sources of radiation; total effective dose is expressed in units of rem (or sievert)

United States Environmental Protection Agency (EPA)

A federal agency responsible for enforcing environmental laws, including Clear Air Act regulations for radionuclide air emissions

Unplanned release

A release of radionuclides to the environment that was not anticipated
