Contemporary issues over the prospective risks of electric and magnetic fields in the house and office are comprehensively addressed inside of this booklet. The chapters include special study at the organic results of electrical and magnetic fields, and facts for and opposed to any interplay of electromagnetic fields (EMFs) and organic systems.
- The relative probability of publicity to EMFs
- Putative behavioral and neural results of EMFs
- EMF results on cells
