A comparison is made with the<br />international safety guidelines given by World Health Organization and International Commission on Non-ionizing Radiation Protection.<br />Results: The penetrated electric field and SAR by some tissues at frequencies 1377, 1404, 1485, 1512, and 1530 kHz of electromagnetic waves are<br />computed.<br />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<br />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<br />radiation is harmful for blood, body fluid, cerebella spinal fluid, eye sclera, gall bladder, gall bladder bile, gland, lung inner, lymph, mucous membrane,<br />pancreas, stomach, testis and vitreous humor tissues at depths 0.1, 0.2 and 0.3 mm, respectively.<br />Keywords: Induced electric field, Specific absorption rate, Thermoregulatory mechanism and broadcasting antenna.</p><p> </p> ER -
