新β射线厚度和重量测定仪美国ＮＤＣ系统公司出品的一种β射线测定仪，可用来高精度地测定厚度或重量。由于该仪器使用一种新研制的超高效检测器，使该公司可能大幅度缩小放射源装置的尺寸。该公司声称，这种技术中的新突破，导致该设备结构上更为紧凑和降低所需的放射剂...
New β-ray thickness and weight detector The United States NDC Systems produced a β-ray detector, can be used to determine the thickness or weight with high accuracy. Because the instrument uses a newly developed ultra-efficient detector, the company may significantly reduce the size of the radioactive source device. The company claims that a new breakthrough in this technology has resulted in a device that is structurally more compact and reduces the need for radiopharmaceuticals ...
