Radiotherapy is the main treatment method for malignant tumors of the head and neck, especially nasopharyngeal carcinoma, hypopharyngeal carcinoma, tonsil carcinoma and oral floor carcinoma. Radiotherapy can cause oral mucosal damage, which not only affects the quality of life of patients after radiotherapy, but also forces them to interrupt radiotherapy in severe cases, which affects the curative effect. Therefore, our hospital used interleukin-11 combined with Kangfuxin liquid to treat oral mucosal injury caused by head and neck radiotherapy, and achieved good curative effect, which is reported below.

Individual dose monitoring of radiation workers is an important part of radiation protection, and also an important content of occupational health monitoring of radiation workers. Personal dose monitoring data is an important scientific basis for objective evaluation of radiation workplace protection level, management level and occupational radiation disease diagnosis. The personal dose monitoring of external exposure of some radiation workers in Inner Mongolia Autonomous Region from 2004 to 2014 is analyzed and reported as follows.

In 1837, the French stage artist L.J.M. Daguerre invented the technique of photography that retains images by using silver-containing chemicals that change when exposed to light^[1,2]。 In 1869, William Crookes, a British physical chemist, discovered a "mist" in the laboratory's photosensitive plate while studying the Crookes tube. At that time, he complained that it might be caused by a packaging defect-"light leakage". Apparently, William Crookes was a pioneering researcher of the cathode ray phenomenon, but he was not aware of the existence of X-rays at that time. In 1894, the German physicist Philipp von Lenard improved the Crookes tube (Figure 1), he touched the cathode ray on the wall of the tube where the fluorescence was emitted, and replaced the original glass with a thin aluminum sheet. As a result, he found that the "fluorescence" emitted from the cathode ray tube penetrated the thin aluminum sheet and shot outside.
