As Low As Reasonably Achievable (ALARA)
Florida Tech ALARA Program
Rules and regulations for protection against radiation hazards are established by Chapter 64E-5 Florida Administrative Code (FAC) and are a condition of our license. These rules specify limits for radiation exposure and are based upon the principle of keeping exposures As Low As Reasonably Achievable (ALARA).
All suspected or known cases of exposures exceeding the limits in table below must be reported immediately to Environmental Health & Safety(EH&S) Radiation Safety Officer(RSO) at 321-674-8889 or the EH&S Director at 321-674-7715 or firstname.lastname@example.org.
Authority of Radiation Safety Officer (RSO)
Per our radioactive materials license (issued by the Florida Department of Health Bureau of Radiation Control), the RSO has the authority to suspend operations or require changes to protocols out of compliance with radiation safety regulations and the provisions of the license.
Maximum Permissible Levels of Radiation in Restricted Areas
A restricted area is one in which access is controlled to allow authorized users.
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 any individual to receive in any period of one calendar month or quarter, a radiation exposure (dose) in excess of the action levels specified in the Exposed limits Table. Action levels at Florida Tech are defined as 10% of the exposure limits per regulation.
2). Notification to Individuals of Exposures
The RSO will maintain exposure records for individuals that require monitoring. The RSO will notify each individual if exposure limits meet or exceed the action levels on the Table. Investigations will be conducted by the RSO to determine the cause of the exposure. A written response indicating corrective action to be taken to prevent future exposure is required by the individual.
