Title 3701:1 - Radiation Control

Section 3701:1-52-07 - Performance criteria for sealed sources
Current through all regulations passed and filed through March 18, 2024
(A) The requirements for sealed sources installed after July 1, 1993:
(B) The test source must be held at minus forty degrees celsius for twenty minutes, six hundred degrees celsius for one hour, and then be subjected to a thermal shock test with a temperature drop from six hundred degrees celsius to twenty degrees celsius within fifteen seconds.
(C) The test source must be twice subjected for at least five minutes to an external pressure (absolute) of two megapascals.
(D) A two-kilogram steel weight, 2.5 centimeters in diameter, must be dropped from a height of one meter onto the test source.
(E) The test source must be subjected three times for ten minutes each to vibrations sweeping from twenty-five hertz to five hundred hertz with a peak amplitude of five times the acceleration of gravity. In addition, each test source must be vibrated for thirty minutes at each resonant frequency found.
(F) A fifty gram weight and pin, 0.3 centimeter pin diameter, must be dropped from a height of one meter onto the test source.
(G) If the length of the source is more than fifteen times larger than the minimum cross-sectional dimension, the test source must be subjected to a force of two thousand newtons at its center equidistant from two support cylinders, the distance between which is ten times the minimum cross-sectional dimension of the source.
