Conduct of Radiological Work
On-site operations with devices containing sealed sources for radiographic use should be conducted in
accordance with the requirements contained in Title 10 CFR part 34, Licenses for Radiography and Radiation
Safety Requirements for Radiographic Operations.
ANSI N43.3, American National Standard for General Radiation Safety-Installations Using Non-Medical X-
Ray and Sealed Gamma-Ray Sources, Energies up to 10 MeV, establishes acceptable guidelines for on-site
operations with devices other than sealed sources for radiographic use.
On-site operations conducted by off-site contractors should be approved by line management in coordination
with the site radiological control organization. This process should ensure the contractor has a valid Nuclear
Regulatory Commission or Agreement State license and that the operational and emergency procedures are
current and available.
Safety devices and interlocks at fixed installations that are required to ensure compliance with 10 CFR 835.501
shall be operational prior to and during generation of a radiation field. Operational status should be verified by
testing. Safety devices and interlocks should be fail-safe.
