Current methods of radiation safety are characterized by age-old hypotheses that claim low doses of radiation, such as those received in diagnostic imaging and cancer treatment, increase the risk of cancer. The linear no-threshold hypothesis dates back to 70 years and has not been scientifically validated, yet it remains the driving force behind current regulatory policies concerning radiation exposure. The linear no-threshold hypothesis has birthed the "as low as reasonably achievable" concept that is commonly practiced in medical professions to limit radiation exposure. Both perpetuate an unscientific radiophobia stigma, while undermining the more likely result of stimulation of protective responses from the low doses of radiation. This article serves to reemphasize the fallacies of carcinogenic risk and to highlight the possible benefits of low-dose exposure in hopes of invalidating the concerns of physicians, the diagnostic imaging technologists, and patient populations that are subject to diagnostic imaging and cancer radiation therapies.
当前的辐射安全方法以古老的假设为特征,这些假设声称低剂量的辐射,如在诊断成像和癌症治疗中所接受的辐射,会增加癌症的风险。线性无阈值假设可以追溯到 70 年前,尚未得到科学验证,但它仍然是当前有关辐射暴露的监管政策的背后驱动力。线性无阈值假设孕育了“尽可能低”的概念,该概念在医学专业中被广泛应用于限制辐射暴露。这两者都延续了一种不科学的辐射恐惧症的污名,同时破坏了更有可能出现的低剂量辐射刺激保护反应的结果。本文旨在强调致癌风险的谬误,并强调低剂量暴露的可能益处,以期消除医生、诊断成像技术人员和接受诊断成像和癌症放射治疗的患者群体的担忧。
