The Emmy-nominated HBO mini-series “Chernobyl,” which is a dramatized account of the 1986 nuclear power plant disaster, has rekindled conversation about the accident, its subsequent cleanup and the long-term impacts on people living near the power plant.
UC San Francisco’s Lydia Zablotska, MD, PhD, grew up in Ukraine, trained as physician in Belarus, and has studied the long-term health impacts of radiation exposure on the Chernobyl cleanup workers, local children and others in the region. Her research helped uncover the connection between radiation exposure, thyroid conditions and leukemia, and remains relevant to global health today.
We talked with her about the real-life health impacts from the disaster portrayed in the HBO miniseries. The following answers have been edited for length and clarity.
What kind of radiation were people exposed to at Chernobyl?
The first responders, including firefighters and nuclear workers who tried to put out the multiple fires and prevent the explosion of other reactors at the nuclear power plant, were exposed to large doses of gamma radiation. Gamma radiation originates during the decay of radioactive isotopes of uranium or plutonium used as a nuclear fuel in nuclear power plants. As a result of decay, packets of electromagnetic radiation, which consist of high-energy photons, are emitted and could penetrate body tissues and cause damage to cells and their genetic material. Subsequently, DNA mutations could lead to the development of cancer.
