Low Weight
The GammaMat SE is a gamma ray projector that has a uniquely low weight and unrivalled portability. It can be loaded with up to 4.44 TBq of Se-75. The weight of this container is only 7.2 kg (16 lb).
Accessories
The broad range of available accessories for varying applications facilitate streamlined daily inspection work. Special low-weight tungsten collimators for panoramic and directional beam characteristics are available.
Regulatory Approvals
The GammaMat SE gamma ray projector using Se-75 has been designed to comply with the latest versions of the national and international safety standards including ISO 3999:2000.
Unparalleled Safety
A green/red indicator shows whether the source is in the safe position. This indicator is easily visible, even from a distance.
Radiation Characteristics
The Se-75 gamma ray spectrum covers the energy range from 66 keV to 401 keV. Two lines of high intensity, at 137 keV and 265 keV, dominate the spectrum. The radiation characteristics are between Yb-169 towards the lower energies, and Ir-192, towards the higher energies. This makes Se-75 the ideal choice for gamma radiography for a steel wall thickness range of approximately 5 to 30 mm (0.2" to 1.18"). Se-75 provides significantly higher image quality than Ir-192.
