Microwave ovens typically operate at a frequency of around 2.45 gigahertz (GHz), which corresponds to a wavelength of approximately 12.24 centimeters. This frequency is commonly referred to as the Industrial, Scientific, and Medical (ISM) band, specifically allocated for microwave ovens and other applications.
In terms of regulations, the specific limits for the electromagnetic radiation emitted by microwave ovens are determined by regulatory bodies such as the Federal Communications Commission (FCC) in the United States and similar organizations in other countries. These regulations aim to ensure that microwave ovens operate within safe levels of electromagnetic radiation to protect human health and prevent interference with other electronic devices.
The FCC in the United States sets the maximum permissible exposure limits for microwave ovens based on the guidelines established by the Institute of Electrical and Electronics Engineers (IEEE) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP). These guidelines consider factors such as the specific absorption rate (SAR) and exposure limits for different parts of the body.
It's important to note that microwave ovens are designed and manufactured to comply with these regulations, and they undergo testing and certification processes to ensure their safety before being sold to consumers.
If you have concerns about the safety or specific emission levels of a microwave oven, it's recommended to consult the product's documentation or reach out to the manufacturer for more detailed information.
