Jens Scheer (30 May 1935 – 18 July 1994), was a physicist, professor of nuclear physics at the University of Bremen and one of Germany's best-known anti-nuclear activists.
For reason of his KPD-membership and his political activities, Scheer was threatened in 1975 with the loss of his academic position at the University of Bremen and an interdiction of enacting his profession, as membership in the KPD and his position as university professor were considered incompatible.
The legal proceedings lasted for about five years, after which the final verdict was the payment of a fine.
[1] One of Scheer's main research interests was low-level radiation and its effects on human beings.
He claimed that radiation exposure at critical moments in life weakens the immune system, thus leading to a higher susceptibility to infectious diseases.
