Sand for high-dose dosimetry using the EPR technique.
The electronic paramagnetic resonance (EPR) technique was utilized to study sand samples from different Brazilian beaches for high-dose dosimetry. Sand also contains concentrations of heavy minerals. Sand samples were studied in relation to their main dosimetric properties: response reproducibility, reutilization, batch uniformity, detection range and dose response. The EPR signal grows significantly as a function of absorbed dose for g=1.999. All studied sand samples can be used as EPR dosimeters for different applications in medical, agricultural and industrial areas.
