Thomas E. Levy 建议在接受乳房X光检查、X光检查等使用辐射的检查前，尽可能多摄入维生素C。
„在接受这类辐射前，尽可能多摄入维生素C总是有益的，因为预防损伤总比损伤发生后再修复容易。与用维生素C治疗其他疾病一样，无论目的是预防还是修复，剂量都最好宁高勿低。”It is always good to get as much vitamin C on board as possible before such encounters, as it is always easier to prevent damage than to repair it after it has occurred. Like with any other medical condition being treated with vitamin C, it is always best to err on the high side in dosing, whether the intent is to prevent or to repair.
Thomas E. Levy 写道，抗氧化剂疗法可以治疗有限的一次性辐射暴露，但他并没有说这种疗法适用于持续暴露于高剂量辐射的情况。
„短暂且有限的辐射暴露很容易通过抗氧化剂疗法处理。对于持续不断、无法消散的高剂量辐射暴露，不能指望任何疗法都能使其缓解。
日本的 Atsuo Yanagisawa 医生发现，即使是中等剂量的维生素C，也能阻止癌症风险评分升高。这项观察持续了一段时间，涉及四名直接进入受损核电站进行修复工作的人员。癌症风险评分与辐射损伤细胞释放游离DNA有关。”Single limited radiation exposures are easily treated by antioxidant-based protocols. Ongoing, high-dose radiation exposures that do not dissipate cannot be expected to relent to any therapy.
Dr. Atsuo Yanagisawa of Japan showed that even moderately-dosed vitamin C was able to prevent the Cancer Risk Score, associated with the release of free DNA from radiation-damaged cells, from increasing during an extended treatment period on four workers who went directly into the damaged plant to effect repairs.
Thomas E. Levy 引用的研究显示，维生素C单独使用或与其他抗氧化剂合用，可能阻止或逆转辐射造成的损伤。
„大量研究还显示，无论是否与其他抗氧化剂合用，维生素C都能在试管实验、实验动物以及接受放射治疗（例如癌症放疗）的患者中，阻止和／或逆转辐射暴露造成的损伤。”A sizeable body of research has also shown that vitamin C, with or without other antioxidants, has been able to block and/or reverse the damage inflicted by radiation exposure in the test tube, in test animals, and in patients receiving radiation therapy, as for cancer.
Thomas E. Levy 介绍了对四名接触辐射的工作人员的观察：他们服用维生素C并继续补充后，癌症风险指标没有升高。
„日本的 Atsuo Yanagisawa 医生发现，即使是中等剂量的维生素C，也能阻止癌症风险评分升高。这项观察持续了一段时间，涉及四名直接进入受损核电站进行修复工作的人员。癌症风险评分与辐射损伤细胞释放游离DNA有关。”Dr. Atsuo Yanagisawa of Japan showed that even moderately-dosed vitamin C was able to prevent the Cancer Risk Score, associated with the release of free DNA from radiation-damaged cells, from increasing during an extended treatment period on four workers who went directly into the damaged plant to effect repairs.
„显然，避免不必要的电离辐射暴露更好，但受福岛核事故影响的人们无法避免污染。抗氧化剂：自由基清除剂。顾名思义，自由基清除剂会清除辐射产生的有害自由基。自由基清除剂更常用的名称是抗氧化剂。抗氧化剂可以补回被电离辐射从分子中夺走的电子。”While avoiding unnecessary exposure to ionizing radiation is clearly preferable, people affected by Fukushima do not have the luxury of avoiding contamination. Antioxidants: Free-Radical Scavengers Free-radical scavengers, as the name suggests, mop up the damaging radicals produced by radiation. The more common term for free radical scavenger is antioxidant. Antioxidants replace the electrons stripped from molecules by ionizing radiation.
„维生素C可以减轻辐射的副作用。维生素C可以减轻术后炎症和感染，并缩短愈合时间。癌症患者在接受放射治疗或化疗期间可以并且应该服用抗氧化剂和其他营养补充剂。维生素C和其他营养素可以减轻副作用，实际上还能提高化疗和放疗的效果。他说：“维生素C有两种作用：它能增强放疗和化疗的有益效果，同时减轻不良影响。””Vitamin C reduces the side effects of radiation. Vitamin C reduces post-surgical inflammation and infection, and reduces healing time. Cancer patients can and should take antioxidants and other nutritional supplements while undergoing radiation therapy or chemotherapy. Vitamin C and other nutrients reduce side effects, and actually improve the results with both chemo and radiation. He says, "Vitamin C has two effects. It increases the beneficial effects of radiation and chemotherapy and decreases the adverse effects.
„16名年龄在32至59岁之间的男性，在受辐射污染的区域工作了5至6周，负责收集受污染的水、测量辐射水平、操作重型机械和清除碎片。研究人员采集了血液样本，用于检测全血细胞计数和血液生化指标、血浆游离DNA水平以及47种癌症相关基因的表达情况。四名工作人员在进入污染区前接受了静脉注射维生素C（25,000 mg），并在工作期间持续服用抗氧化补充剂；他们的游离DNA和总体癌症风险均无显著变化。”Sixteen men aged between 32 and 59 years worked 5 to 6 weeks in a radiation contaminated area, collecting contaminated water, measuring radiation levels, operating heavy machinery, and removing debris. Blood samples were obtained to measure whole blood counts and blood chemistry, plasma levels of free DNA, and 47 cancer related gene expressions. Four workers who took intravenous vitamin C (25,000 mg) therapy before they went in, and continuously took anti-oxidative supplements during the working period, had no significant change in both free DNA and overall cancer risk.
