plastic scintillation detector application Supplier & manufacturers |

Solid detectors are commonly used for gamma-ray spectroscopy, material assay, activation analysis, radon canister counting, thyroid uptake measurements, and health physics applications for energies greater than 15 keV. End well and through-side well-configured detectors are highly efficient for measuring activity of small-sized sources and in higher energy emitting isotope measurements. End well detectors are the most efficient (typically greater than 80%) because the scintillator surrounds the sample. Through-side well detectors are ideal when space is limited and is the second most efficient configuration, and are ideal for radioimmunoassay and fuel rod monitoring applications. Square or Rectangular Cross-Section provides a 27% increase in volume over a cylindrical scintillator of the same diameter and length. This increases detector efficiency while keeping package size and shielding requirements down. They are easily stacked in arrays for increased efficiency for applications such as aerial survey, whole-body counting, security portal monitoring and medium and high energy physics. Thin radiation entrance window designs are used for low-energy and X-ray detection applications. A thin entrance window allows measurements down to 3 keV while a thin crystal reduces sensitivity to background radiation.
