57Co Line sources

Sources for Mossbauer Spectrometry

Used in physics, chemistry and biology to determine the structure of materials and mechanisms of interaction. The proposed sources could be either 57Co or 119Sn. The standard matrices are in rhodium (for 57Co) or CaSnO3 (for 119Sn), the beryllium window ensuring the absence of radioactive contamination.

Sources for Process control

For nuclear fuel cycle facilities: 60Co, 137Cs, AmBe et 252Cf sources.

Sources for Construction and agriculture:

Neutron and gamma sources to measure moisture or soil density. The sources are used to determine the water content of bulk materials (agricultural silo, gravel, wood chips…) or soil density by measurement with a neutron emitting source (AmBe type) or by association with a 137Cs source and an AmBe source.

Sources for Industrial gauges:

  • Paper weight measurements (beta sources of 85Kr and 147Pm),
  • thickness and density measurements (beta sources of 90Sr, 85Kr and 147Pm),
  • level control (sources of 241Am and 137Cs).

Sources for X-ray fluorescence

For the detection of lead in paints. The sources proposed by LEA are made of 109Cd, 57Co from 4.9 mCi (180 MBq) to 23 mCi (850 MBq). These capsules are made of stainless steel.
