Idea about activation products may give analytical idea about the neutron spectrum. This may crudely help to estimate fission yield and related parameters. In atomic bomb survivors study somewhat similar approach was used for neutron component measurement and gamma component was estimated using roof tiles etc. By TL technique. Variety of activation products has different reaction thresholds and cross section. Majority of such isotopes do not occur naturally.

Height is difficult from activation products. Neutron distribution is influenced by shape and angle of the device and structural components of the device. Neutron distribution does not necessarily follow the blast distribution.
