Custom crystal & detector assemblies. The longtime work horse for BNC’s SAM III generation and SAM 940, sodium iodide (NaI) crystals are the most widely used scintillation material for gamma-ray spectroscopy. Their high light output and the excellent match to the sensitivity of photomultiplier tubes, provide good, economical energy resolution.

905系列NaI（Tl）闪烁辐射探测器 与闪烁体相互作用的伽马射线产生光脉冲，该光脉冲由光电倍增管（PMT）转换成电脉冲。 PMT由一个光电阴极、一个聚焦电极和10个或更多的倍增电极组成，这些倍增电极用来成倍增加每个倍增电极上的电子数量。

2015年9月10日 · So these are two uses of NaI detectors – measuring contamination levels (in counts per minute or counts per second) and identifying radionuclides by measuring gamma energies – now for a third, measuring radiation dose rate. Radiation dose rate is a measure of the amount of energy deposited in an object.

A NaI (Tl) scintillation counter is a radiation detector that uses the effect known as scintillation. Scintillation, which occurs in the NaI (Tl) crystal, is a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an …

The 802 series of NaI(Tl) detectors provides high efficiency and uniform response on both the cylindrical and well configurations. These detectors have a proven record of long term reliability and stability. Any Model 802 detector assembly plugs directly into the Model 2007 Tube Base which provides power for the photomultiplier tube.

The NAIS-3x3 NaI (Tl) detector is LED temperature-stabilized*, eliminating the peak-shift problems inherent in scintillation detectors. This makes the NAIS-3x3 detector suitable for use in non-air-conditioned rooms as well as in field applications.

NaI(Tl) detectors. NaI(Tl) is a great scintillator for high-rate (< 500kcps) counting and precision spectroscopy. This low-cost scintillator is the work horse of the industry. But it requires some care in packaging and handling when used in mobile devices as it is delicate and sensitive to mechanical and thermal shock.

NaI (Tl) (thallium-doped sodium iodide) is the most widely used scintillation material. NaI (Tl) as the scintillator is used in scintillation detectors, traditionally in nuclear medicine, geophysics, nuclear physics, and environmental measurements. The iodine provides most of the stopping power in sodium iodide (since it has a high Z = 53).

Complete assemblies including the scintillator and PMT are available. Learn more about ORTEC's 905 Series NAI (TI) Scintillation Radiation Detector and its capabilities.

Polyscin® NaI(Tl) scintillation crystals are widely recognized as suitable alternatives to single-crystal scintillators in many applications where thermal and mechanical shock are encountered, such as oil and gas exploration. This crystal offers ruggedness combined with a scintillation performance identical to single-crystal NaI(Tl).
