Ionising radiation was proven to be bad for dogs. Does that mean it’s good for humans?

The effects of ionizing radiation on domestic dogs: a review of the atomic bomb testing era, Wiley Online Library , Gabriella J. SpatolaElaine A. Ostrander Timothy A. Mousseau 13 May 2021 


Dogs were frequently employed as laboratory subjects during the era of atomic bomb testing (1950–1980), particularly in studies used to generate predictive data regarding the expected effects of accidental human occupational exposure to radiation. The bulk of these studies were only partly reported in the primary literature, despite providing vital information regarding the effects of radiation exposure on a model mammalian species. Herein we review this literature and summarize the biological effects in relation to the isotopes used and the method of radionuclide exposure. Overall, these studies demonstrate the wide range of developmental and physiological effects of exposure to radiation and radionuclides in a mid‐sized mammal.

………………………………………………III. CONCLUSIONS

  1. Domestic canines commonly share the same environment, lifestyle, and exposure to pollutants as their human counterparts (Mazzatenta et al., 2017; Ostrander et al., 2017). Coupled with their larger body size and longer lifespan compared to other frequently used model organisms, this makes the canine model a useful tool in studying radiation‐induced diseases.
  2. Frequent effects of radiation exposure in dogs include haematological changes, infertility, and cancer of the bone, liver, lung, and blood, among others. Effects depend on the radionuclide, method of exposure, age at exposure, dose rate, and total exposure dose.

    1. With an increasing demand for nuclear power comes a higher risk of nuclear accidents, and studies of radiation exposures in domestic dogs have provided valuable information for understanding the repercussions for accidentally exposed populations.
    2. Although experiments done in a laboratory setting have proved illuminating, more studies are needed on natural populations affected by past radiological disasters in order to further our understanding of how laboratory results may apply, as such populations are affected by potentially confounding environmental factors. In addition, the vast background knowledge provided by early radiation studies on dogs could allow meaningful conclusions to be drawn regarding the application of laboratory results to natural populations………………
