The interaction of gamma radiation with drugs used in cholinergic medications.

Pharmacological medications can reduce the radiation damage in the organism when applied in the stage before or after exposure to radiation. Cholinergic drugs are a category of pharmaceutical agents acting on the neurotransmitter acetylcholine, the primary neurotransmitter in the parasympathetic nervous system. In this investigation, some gamma radiation interaction parameters namely mass attenuation coeffıcients (), effective atomic number () and electron densities () of 12 cholinergic system drugs have been calculated in the energy range 1 KeV-100 GeV.
