Objective: Theoretical studies are made for the specific absorption rate (SAR) in consequences of induced electric fields due to radio broadcasting
tower at 100 m distance.
Methods: The penetrated electric fields and SAR inside human body tissues are calculated for different frequencies. A comparison is made with the
international safety guidelines given by World Health Organization and International Commission on Non-ionizing Radiation Protection.
Results: The penetrated electric field and SAR by some tissues at frequencies 1377, 1404, 1485, 1512, and 1530 kHz of electromagnetic waves are
Conclusion: According to permissible limit the frequencies 1377, 1404, 1485, 1512 and 1530 kHz of 20 kW EM radiations at 100 m distance are safe
for tissues bladder, blood vessel, brain white matter, fat, heart, lung outer and mucous membrane at depths 0.1, 0.2 and 0.3 mm respectively. And this
radiation is harmful for blood, body fluid, cerebella spinal fluid, eye sclera, gall bladder, gall bladder bile, gland, lung inner, lymph, mucous membrane,
pancreas, stomach, testis and vitreous humor tissues at depths 0.1, 0.2 and 0.3 mm, respectively.
Keywords: Induced electric field, Specific absorption rate, Thermoregulatory mechanism and broadcasting antenna.
