--Table of Contents
 
                      Subpart A_General Provisions
 
Sec. 36.2  Definitions.

    Annually means either (1) at intervals not to exceed 1 year or (2) 
once per year, at about the same time each year (plus or minus 1 month).
    Doubly encapsulated sealed source means a sealed source in which the 
radioactive material is sealed within a capsule and that capsule is 
sealed within another capsule.
    Irradiator means a facility that uses radioactive sealed sources for 
the irradiation of objects or materials and in which radiation dose 
rates exceeding 5 grays (500 rads) per hour exist at 1 meter from the 
sealed radioactive sources in air or water, as applicable for the 
irradiator type, but does not include irradiators in which both the 
sealed source and the area subject to irradiation are contained within a 
device and are not accessible to personnel.
    Irradiator operator means an individual who has successfully 
completed the training and testing described in Sec. 36.51 and is 
authorized by the terms of the license to operate the irradiator without 
a supervisor present.
    Panoramic dry-source-storage irradiator means an irradiator in which 
the irradiations occur in air in areas potentially accessible to 
personnel and in

which the sources are stored in shields made of solid materials. The 
term includes beam-type dry-source-storage irradiators in which only a 
narrow beam of radiation is produced for performing irradiations.
    Panoramic irradiator means an irradiator in which the irradiations 
are done in air in areas potentially accessible to personnel. The term 
includes beam-type irradiators.
    Panoramic wet-source-storage irradiator means an irradiator in which 
the irradiations occur in air in areas potentially accessible to 
personnel and in which the sources are stored under water in a storage 
pool.
    Pool irradiator means any irradiator at which the sources are stored 
or used in a pool of water including panoramic wet-source-storage 
irradiators and underwater irradiators.
    Product conveyor system means a system for moving the product to be 
irradiated to, from, and within the area where irradiation takes place.
    Radiation room means a shielded room in which irradiations take 
place. Underwater irradiators do not have radiation rooms.
    Radiation safety officer means an individual with responsibility for 
the overall radiation safety program at the facility.
    Sealed source means any byproduct material that is used as a source 
of radiation and is encased in a capsule designed to prevent leakage or 
escape of the byproduct material.
    Seismic area means any area where the probability of a horizontal 
acceleration in rock of more than 0.3 times the acceleration of gravity 
in 250 years is greater than 10 percent, as designated by the U.S. 
Geological Survey.
    Underwater irradiator means an irradiator in which the sources 
always remain shielded under water and humans do not have access to the 
sealed sources or the space subject to irradiation without entering the 
pool.
