AmBe Neutron Source Integrity Testing

QSA Global, Inc.'s sealed AmBe neutron sources are manufactured with high-performance materials, such as MP35N and 17-4 PH stainless steel for outstanding durability, corrosion resistance, and extremely high tensile strength. 17-4 PH stainless steel provides magnetic properties to facilitate source retrieval. All of our AmBe sources are tested according to ISO 2919/ANSI N43.6 standards. We can perform high-pressure testing up to 60,000 PSI (414 MPa), which is well beyond the class 6 pressure requirement of 24,656 PSI (170 MPa). We can also perform temperature testing to the maximum class 6 requirement of 800°C for 1 hour. The following are just a few of the tests we perform:

ISO 2919 Class 6 Puncture Test: 2.2 lbs (1 kg) from 3.3 ft (1 m) or equivalent imparted energy

ISO 2919 low-temperature test with liquid nitrogen (-196°C)

Post low-temperature test with liquid nitrogen

ISO 2919 Class 6 High Temperature test to 800°C for 1 hour

ISO 2919 Class 6 Temperature Test: Thermal shock from 800°C to 20°C (in water)

Post ISO 2919 Class 6 thermal shock test
