Web24 sep. 2024 · Additionally, the International Commission on Non-Ionizing Radiation Protection (ICNIRP, 2024) recommends a limit of 2 W/kg for head and trunk exposure over 10 grams of tissue. Based on the recommendation, each country and wireless device manufacturer produce devices which adhere to the SAR limits. WebWe can assume, for example, that absorption of enough radiation to produce an increase of about 6C in body temperature would be fatal. Since the average 70-kilogram human is 80% water by weight, we can use the heat capacity of water to calculate that it would take about 1.5 million joules of non-ionizing radiation to kill the average human.
