In this study (Davis et al., 1989), the all cancer mortality rate was reported for TB patients who were exposed to fluoroscopic radiation and those who were not exposed to the radiation. Note: SMR = Standardized Mortality Ratio Based on the data, for the fluoroscopically exposed patients, males

A small amount of radiation (low-dose radiation) would cause a small amount of DNA damage which can result in mutations. However, DNA damage and mutations happen all the time even without radiation exposure, because of natural processes in our bodies, and this damage is much more than the damage tha

Improved survival of non-Hodgkin’s Lymphoma patients was observed when they were subjected to 10 or 15 cGy total-body or half-body irradiation (TBI or HBI) interspersed between radiation treatments to the tumor (Total dose=1.5 Gy) (Sakamoto, 2004). These data indicate that low radiation doses redu

Many publications have claimed that increased residential radon levels increase lung cancer risk. However, there is a major problem with such publications. Whereas high-dose radiation, received in a short time, has been observed to increase cancer risk as observed in the atomic bomb survivors, low

The field of radiology has evolved considerably since the time X-rays were first used for diagnosis in the early days of radiology. The cancer risk due to high radiation doses was recognized following the experience of initial radiologists, and efforts were made to reduce the radiation dose. The ave

Second cancers per kg of tissue is lower in parts of body exposed to low-dose radiation in radiation therapy patients when compared to the parts of the body that had no radiation exposre This study (Tubiana et al., 2011) was carried out on a French-United Kingdom cohort of 5,000 survivors of a chil

Low-dose radiation, when applied multiple times to the whole body during several weeks, has been observed to produce a cancer therapeutic effect. The survival of cancer patients treated with low-dose radiation is similar to (Chaffey et al., 1976; Hoppe et al., 1981) or better than (Choi et al., 197

Immune system plays a very important role in preventing cancer, as indicated by the increase in the cancer risk when the immune system is suppressed in organ-transplant recipients and AIDS patients (Oliveira Cobucci, 2012). Immune system response declines rapidly with age (Levin, 2014), qualitat

In 1982, several Co-60 sources were accidentally recycled by the steel scrap industry in northern Taiwan and resulted in contaminated steel products that were used to construct many apartment buildings. The residents of the apartment buildings received exposure to low-level radiation due to the cont

During 1957-1981, many civilian workers overhauled and repaired nuclear-propelled US Navy ships and submarines. Among these workers, the radiation workers had exposure to low-level radiation, and the other workers (non-radiation workers) had no exposure to low-level radiation. The cancer mortality r
