Dosimetry Irradiations at the Laboratory for Nuclear Calibrations (LNK)

The Laboratory for Nuclear Calibrations (LNK) of the Belgian Nuclear Research Centre (SCK•CEN) is the designated metrology laboratory in Belgium for the ionizing radiations, sub-field of dosimetry and is performing secondary standard calibrations and irradiations with ionizing radiations following the requirements of the ISO 17025 quality assurance standard. 

Our offer

LNK performs irradiations of a wide range of samples and dosimetry equipment with relatively low dose rates up to few Sv/h (photons) and few mSv/h (neutrons).

The laboratory is specially designed for dosimetry irradiations and calibrations and follows the ISO 4037 (photons) and ISO -8529 (neutrons) recommendations.

Encapsulated and small size radioactive sources are used for irradiations. Several set-ups are available with different types of collimation systems and beam directions (horizontal, vertical or panoramic 2π beam).

A lot of space is available around the sources; sample size from few mm to tens of cm can be fitted inside the beam while holders and electronic equipment can be kept outside the beam.

Typical irradiations are done for dosimetry equipment, biological samples, material testing.

More details and a list of available beams and dose rates can be found on the main page of the Laboratory for Nuclear calibrations.
