in KNN-LMN non-lead ceramics) causes an increase in the value of the neutron attenuation parameter (
), and a strong relationship is monitored between
and density. Moreover, descending order of
is reported for half-value layer values against gamma photon. From the attained results, it can be concluded that increaisng the rate of x results in the better shielding proficiency in terms of neutron and gamma photon for chosen KNN-LMN-based lead-free ceramics.
