Profile: RMD, Inc. specializes in the manufacturing of testing equipments. Our products include lead paint analyzers, lead tracers, silicon avalanche photodiodes, digital radiography instruments, cesium iodide imaging sensors, CZT arrays, gamma ray imaging systems, medical instruments and quadrant detectors. Our LPA-1 lead paint analyzer is a XRF spectrum analyzing system for the quantitative measurement of lead in paint on any surface. The LPA-1 analyzer provides measurement of lead content in as little as 2 to 4 seconds with a 95% confidence level. Our LPA- 1 method of measurement is based on the spectrometric analysis of lead K-shell X-ray fluorescence within a controlled depth of interrogation. Cadmium zinc telluride (CZT) arrays are compact X-ray and gamma ray detectors that operate at room temperature & provide both spatial & spectroscopic information as well as high detection efficiency & energy resolution over a wide range of photon energies. They are more compact and have superior energy resolution than scintillator/photo-detector spectrometers. CZT arrays applications include high-resolution single photon emission computed tomography (SPECT), nondestructive testing, homeland security and hard X-ray astronomy.
