No misdiagnosis, 100 billion loss per year

Experts say: LED light blue amount will damage the eyes Yangcheng reporter Chenjiang, correspondent Shing, Ye Zhixuan reported: "Our annual error measurement caused by misdiagnosis, resulting in economic losses, the most conservative estimate also amounted to 100 billion yuan, equivalent to one Three Gorges Dam a year."　　"Yesterday is the World Measurement Day," Guangzhou, dean of the Institute of Metrology and Testing technology Zhou Lenbin to this concern about the phenomenon of the national livelihood. The pencil drawing line can measure the weight to commemorate "The 5 20 World Measure Day", is located in the Luogang District Science Science Science "Guangzhou Measurement Laboratory" to open yesterday first.　　Yangcheng Evening News reporter at the scene saw a professional and special measurement laboratory ——— 63 meters long laboratory, equipped with a 50-meter indoor laser baseline, the base is made of tens of thousands of years of granite, designed to calibrate laser rangefinder, scanners, tracking instruments, the value of the instrument is the treasure of the town room. In another 6 "quality comparator" of the small quality laboratory, Guangzhou metrology and Testing technology research Institute Dean Zhou Lenbin introduced: "If the pencil on a piece of paper to draw a line, the quality comparator can be called the weight of that line." "It is learned that such a small precision of quality measurement, in fact, in life can also be useful."　　For example, food, medicine in the heavy metal content standard is very little, but rely on the instrument can measure its weight. Dose not to be able to cause casualties in the hearts of the people understand the measurement, no outside of the "Daily necessities YOUYANJIANGCU Tea" open seven measures. But in Zhou Lenbin and other measurement professionals, measurement is the basis of the whole people's livelihood. For example, in the medical and health problems, the measurement is not allowed to often cause personal casualties. "Radiation therapy for tumors, X-rays and gamma rays is closely related to the therapeutic effect, and if the radiation dose exceeds the standard, the patient's good tissue is burned or damaged, and if the radiation dose is insufficient, the treatment is not achieved."　　"It is understood that our country every year due to erroneous measurement caused by misdiagnosis, resulting in economic losses, the most conservative estimate also amounted to 100 billion yuan." And take the recent popular low carbon market led energy-saving lamps, Zhou Lenbin pointed out that although it has energy-saving, long life and other advantages, but because it is a blue light source, once the Blu-ray more than a certain standard, it will cause damage to the human body, especially the eyes. Unfortunately, at present, there is no corresponding standard for LED light, blue screen, "This is still a blank in China, to rely on the implementation of strict measurement standards, control LED Blu-ray volume." "In order to accurately and quickly detect fresh meat moisture, the Beijing Industrial and commercial system is equipped with the introduction of new infrared meat moisture meter imported from Germany." The picture is for the staff to use the instrument to detect fresh meat water samples.
