Our services

Dosimeter Services is an award-winning service provider that was established in 2017 and SANAS (ISO/IEC 17025:2017) accredited in June 2018

Dosimeter Services won the Elekta Award for best presentation and the SABS Award for Best Research performed in the field of radiation dosimetry at the South African Association of Physicists in Medicine and Biology (SAAPMB) congress in 2019. The research was chosen to be presented at the International Radiation Protection Association (IRPA) conference in Korea in 2020.

We meet the following regulatory requirements :

South African National Accreditation System (SANAS) accredited (T908)
South African Health Products Regulatory Authority (SAHPRA) – Radiation control (DS0908) approved

The work horse (OSL Reader)

The Landauer OSLR 5O reader utilizes a High-Powered Light Emitting Diode (LED) AND Pulsed Optically Stimulated Luminescence (P-OSL) technology to achieve better separation between the optical stimulation spectra (green region):
