PTW-Freiburg operates Germany's first Secondary Standard Dosimetry Laboratory for radiation quantities accredited by the DAkkS, under direct supervision of the National Laboratory. It is also a member of the international SSDL network, organized by the International Atomic Energy Agency IAEA.

We perform radiological calibrations for dosemeters used in radiation therapy, diagnostic radiology and health physics, which are directly traceable to the primary standard. Our calibration lab provides a complete range of radiological calibrations from low X-ray energies up to 60Co and from low to high dose rates and is one of the busiest calibration labs worldwide.

We cooperate closely with official public agencies worldwide, and we participate actively in national and international work groups for the standardization of devices and procedures for dose measurement and quality control in medical radiology.

Knowing what responsibility means.

More than 90 years of product and service excellence in dosimetry - from the first dosemeter in 1922 to the largest range of high-tech solutions for any dosimetry need. That is what PTW stands for.
