Dosimetry

We can perform dosimetry for specialised irradiations and external facilities, traceable back to National Physical Laboratory standard. Dosimeter regularly used:

• Ion cambers
• Gafchromic films (room-light safe, self-developing radiation sensitive film) to determine the 2D variation in dose
       -  EBT3 (0.2 – 10 Gy)
       -  MD-V3 (1 – 100 Gy)
• Thermoluminescence: TLD-100 and TLD-800
• Alanine
• Charged particle detection
    -  CR39 nuclear track detectors
    -  Fluorescent Nuclear Track Detectors (FNTD)
• Spectrometry (gamma-rays and alpha-particles)
• Automated Liquid Scintillation Counting
