Abstract

The aim of the present study is to investigate the effect of exposure of rat’s bone to extremely low frequency magnetic field (0.5 Gauss), fast neutrons FN (10µSV/h) and combined fields of both for a period of 4 weeks at a rate of 8 h/day, 5 days /week. For this purpose, 80 adult male albino rats were divided into four equal groups: group A, (control group), group B (exposed to magnetic field), group C (exposed to FN), group D (exposed to combined fields of magnetic field and fast neutron). After each experiment, bone samples were subjected to the following studies: bone density measurement, evaluation of Ca++ concentration following atomic absorption technique, measurement of mineral content, degree of calcification using FTIR technique & biomechanical testing of bone. Results reveal high significance decrease in bone quality causing brittle bone resulting in osteoporosis.
