Exposure limits for non-ionizing radiation

This paper presents the non-ionizing radiation exposure limits for both occupational worker and general public. It specifies limits of exposure of continuous wave and pulsed field on whole or a part of human body. The dosimetric quantity for measuring exposure limit is decided by the way fields interacts with human body at various frequency ranges. At the lower frequency range of 300 Hz to 1 MHz, relevant dosimetric quantity is the current density expressed in A/m². In the frequency range of 100 kHz to 10 GHz, the appropriate dosimetric quantity is the specific absorption rate (SAR) expressed in W/kg. In the upper frequency range of 6 to 300 GHz, the power density expressed in units of W/m² is considered to be the relevant dosimetric quantity. The Exposure limit mentioned in this paper is derived from various International standards.
