Three Mile Island Fallout Map

The center of this Toxic Plume is located approximately 12 miles southeast of Harrisburg, Pennsylvania, at the Three Mile Island Nuclear Power Plant. This plume was produced by one of the two reactors located at the Three Mile Island plant, after the reactor descended into partial meltdown on March 28, 1979.

  2. Perhaps I missed it. I scanned for a record of wind direction that day. My late father worked at the State Hospital in Hamburg, PA. It was a relatively warm a.m. and he related he drove his vehicle to work with the window down, his arm on the door. Dad said there was a mist in the air and where ever the mist touched his arm, it tingled, almost burned. My sister and I were admitted to the hospital a month later and ended up sharing a room. I was bleeding heavily at age 16, needing 2 units of blood, she had a miscarriage a day after I was admitted. Dad passed from stomach cancer Dec. 30, 1989, age 59, a mere skeleton. There’s way more, including thyroid disease, etc., but I don’t have the energy. We live in Minersville/Pottsville, PA, Schuylkill County area.

      Ms. Curlis, I am so deeply sorry that your family experienced such tragedy from the Three Mile Island meltdown. I am so sorry. My heart goes out to you and your family, your father and your sister’s child. Thank you for sharing your story. Please let me know if there’s anything I can help research or help in advocating for you.

      I hadn’t posted anything about the wind direction on that day, but I just did so now: https://radioactivemonticello.wordpress.com/2018/06/20/three-mile-island-weather/
      There is also an in depth article about the weather in Harrisburg on the day of the disaster, written by Reinhold Steinacker and Ignaz Vergeiner, of the Departments of Meteorology and Geophysics at the University of Vienna and the University of Innsbruck: http://people.iarc.uaf.edu/~datkinson/ATM644/papers/Steinacker_2002.pdf

      I’m not an expert on this matter, but I can try to help connect you to experts to help answer some of your questions. From what I can see from the weather charts, at the time the nuclear plant started failing (4am) the wind had been moving West for at least four hours. By 5am it moved South and was blowing East and North East from 6am into the afternoon, at 5-10 miles per hour. This to me seems to affirm that the wind was moving from Harrisburg in the direction of Hamburg, but I’m not an expert–a professional meteorological analysis would be able to tell for sure.

      In the article I shared above, the authors affirm that it was a relatively warm morning the day of the tragedy. In their conclusion, they write, “The balmy wind and weather conditions during the first few days of the TMI-2 accident were highly unfavorable for plume dispersion. […] Locally very high exposures to radioactive releases due to plume impingement on hill sites are plausible.”

      Thank you again for sharing your experience.

  3. Where are these pictures from? Is it a book that is available for purchase?
