WebIntroduction. Esophageal cancer is one of the most common cancers in China. The 5-year survival rate of esophageal cancer patients after radical surgery is about 20–30%. 1,2 Radical radiochemotherapy is a critical therapy for patients with unresectable cancer. After radiation, the 5-year survival rate can reach up to 27%, 3 which is comparable to surgery. WebIn general, the average annual dose received by radiation workers is found to be considerably lower than the individual dose limits. Good radiation protection practice can thus result in low radiation exposure to workers. At What Level is Radiation Harmful? The effects of radiation at high doses and dose rates are reasonably well documented.
