Luxel+ contains a thin strip of specially formulated aluminum oxide crystalline material within a four-element filter pack that is heat sealed within a laminated, light-tight paper wrapper. All of these components are radio-frequency sealed inside tamper-proof plastic to eliminate possible mishandling, light leakage or lost detection elements.
The Luxel+ dosimeter measures radiation exposure due to X, gamma and beta radiation with optically stimulated luminescence (OSL) technology. The OSL radiation detector inside the Luxel+ dosimeter is the thin strip of specially formulated aluminum oxide (Al2O3) crystalline material.
The luminescence measured during analysis is applied to a dose algorithm that relies on the response ratios between different filter positions within the dosimeter to discriminate between beta and photon (X and gamma) radiation fields to determine exposure results. Dose equivalents arising from exposures to photons (X or gamma rays) will have a deep, lens of eye and shallow value reported. Depending on the energy of the X or gamma rays, these values may or may not be equal. Beta exposures are reported only as a shallow dose equivalent.
