Ex posure to SEMF resulted in increased 45Ca retention in tibias of aged animals only. Levels of serum calcium in young female and male rats were significantly less than in respective aged rats. These were further decreased after 4 weeks of SEM F exposure. SEM F exposure did not change the serum calcium levels in aged rats, and inorganic  phosphates in young and aged animals. Similarly, the levels of tartrate resistant acid and alkaline phosphatase were significantly decreased in young rats, whereas the levels remained unchanged in aged rats or either sex. The results revealed that SEM F of 1mT can prevent bone calcium loss due to aging in animals.</span
