The objective of this work is to obtain preliminary results demonstrating the potential of Optically Stimulated Luminescence Dosimeters (OSLDs) for two types of applications: (a) the determination of staff doses due to scattered radiation in interventional fluoroscopy and (b) the determination of helmet output factors in Gamma Knife ® (Elekta AB.) radiosurgery. These applications represent completely different dosimetric challenges. In interventional fluoroscopy the challenge is the measurement of low doses associated with scattered radiation from a single procedure in a convenient way. To demonstrate the potential of OSL for this type of application, we mapped the dose to an anthropomorphic phantom simulating the physician after a single simulated interventional fluoroscopy procedure. In radiosurgery the challenge is to measure doses for small field sizes with high precision. In this case, we used small OSLDs (2mm in diameter by 0.3mm thickness) to determine the output factors for helmet collimation of 18mm, 14mm, 8mm, and 4mm, showing that the output factor can be obtained with uncertainty <1% (single OSL readout) and in agreement with the literature, except for the controversial case of 4mm collimation. Combined, the results on the application of OSLDs to these two different challenges demonstrate the versatility of the OSL technique.
