Terra Manca at the University of Alberta has an article in The Journal of Religion and Popular Culture titled “L. Ron Hubbard’s Alternative to the Bomb Shelter: Scientology’s Emergence as a Pseudo-science During the 1950s.”
Manca discusses how Scientology presented pseudo-scientific solutions to radiation sickness. L. Ron Hubbard, despite lacking formal scientific training, discredited and critiqued orthodox science while claiming to be an authority in nuclear physics and medicine. Here is the abstract:
In the 1950s, L. Ron Hubbard founded Scientology and offered it as the key to surviving nuclear fallout. Hubbard’s success in promoting his claims depended on his ability to convince some people that Scientology was a unique science with more authority to state the truth than orthodox science. These claims contributed to both Scientology’s and Hubbard’s ﬁnancial well-being, but provided little to no beneﬁt for followers and may have harmed some patients. Despite diminished fears of nuclear holocaust, Scientology continues to promote puriﬁcation programs based on the radiation claims Hubbard made.
