Neutron study of medium transfer bystander effect for a human skin cell line

Neutron irradiations at the McMaster Nuclear Reactor have been performed to study direct and bystander effects for a human skin cell line. The neutrons are produced in the core of the swimming pool type reactor by nuclear fission; they are then partially moderated through water before exiting along a beam tube in the reactor wall. The resultant neutron spectrum has an energy distribution with an average of 1 MeV. The gamma contamination of the …
