ALARA Program

Rules and regulations for protection against radiation hazards are established by the Florida Department of Health Regulation 64E-5 and are a condition of our license. These rules specify limits for radiation exposure and are based upon the principle of keeping exposures ALow AReasonably Achievable (ALARA).

Reporting Requirements

All suspected or known cases of exposure or of exceeded limits must be reported immediately to the Radiation Safety Officer.

Authority of Radiation Safety Officer (RSO)

As per license agreement with the Florida State Bureau of Radiation Control, the RSO had the authority to suspend operations or require facility protocol changes in laboratories where any radiation safety problems are detected.

Maximum Permissible Levels of Radiation in Restricted Areas

A restricted area is one in which access is controlled by the authorized user of radiation

  1. External Radiation Exposure to Individuals
    No user shall possess, use or transfer radioactive materials or use ionizing radiation producing machines in a restricted area in such a manner as to cause an individual to receive in any period of one calendar quarter, a radiation exposure (dose) in excess of the limits specified in the Exposure Limits Table.
  2. Notification to Individuals of Exposures
    The RSO will keep and monitor exposure records on individuals that require monitoring. The RSO will notify each individual if/when exposure limits meet or exceed the “Notification Limits” on the table. Investigations will be conducted by the RSO if the “trigger limits” specified in the table are exceeded. When notifications are issued, a written response is required.
