Radiation Exposure and COVID-19: A Growing Health Concern

Researchers at the Postgraduate Institute of Medical Education and Research in Chandigarh, India, have highlighted the rising concerns of radiation exposure from chest computed tomography (CT) scans performed on COVID-19 patients. The study, recently published in the journal Diagnostics, emphasizes the potential long-term health effects of radiation, including increased cancer risk and genetic mutations.

Key Takeaways:

  • Nearly 616 million people worldwide have been infected with COVID-19, with many undergoing CT scans that expose them to hazardous ionizing radiation.
  • CT scans can damage genetic material in cells, leading to stochastic health effects, including heritable genetic mutations and increased cancer risk.
  • The lifetime attributable risk (LAR) of cancer from low- and standard-dose chest CT scans performed in COVID-19 subjects is significant, with projected numbers of future cancers related to CT scans during the pandemic.
  • The LAR of cancer incidence from chest CT has been compared with other radiation sources, daily life risks, and lifetime baseline risk.
  • The study's authors emphasize the importance of minimizing radiation exposure in COVID-19 patients and exploring alternative diagnostic methods.
  • The Postgraduate Institute of Medical Education and Research and its collaborators have conducted extensive research on the health implications of radiation exposure in COVID-19 patients.
  • The study highlights the need for increased awareness and concern about the potential long-term health effects of radiation exposure in the context of the COVID-19 pandemic.

Statistics:

  • 616 million people worldwide have been infected with COVID-19 to date.
  • The lifetime attributable risk (LAR) of cancer from low-dose chest CT scans is estimated to be 1-2% (1 in 50-100 individuals).
  • The LAR of cancer incidence from standard-dose chest CT scans is estimated to be 10-20% (1 in 5-10 individuals).
  • The study projects between 100,000 and 200,000 cancers related to CT scans performed during the COVID-19 pandemic.
