Other studies of additional cancer cases and mortality resulting from the radiological release have produced differing results. In 2007, the 50-year anniversary of the fire, new academic research into the health effects of the incident was published by Richard Wakeford, a visiting Professor at the University of Manchester's Dalton Nuclear Institute, and by former UK Atomic Energy Authority researcher, John Garland. Their study concluded that because the actual amount of radiation released in the fire could be double the previous estimates, and that the radioactive plume actually travelled further east, there were 100 to 240 cancer fatalities in the long term as a result of the fire.
