Microwave heating systems for industrial uses, notably for food and farm goods have been extensively developed. Microwave energy is now being used in many ways, with greater focus on consumption. If utilized for a consumer product as a power source, microwaves are typically employed in a totally shielded enclosure that does not allow access while the microwave source is running. The radio frequency (RF) leakage above 5mW (+ 10 dBm) is dangerous to humans, according to the World Health Organization (WHO) guideline. This manuscript focuses on the low cost hand held device for detection of microwave energy radiation because it is very hazardous for human body. This kind of device will be very helpful for clean and green society.

“…Leakage is then measured using the same meter that was used in the survey, at different distances from the inserted piece of paper. Measurement was carried out five times and figure 4 shows the average measured power density, decreasing with distance from the oven along with the theoretically expected 1/r 2 decrease of the radiated power density from the oven (Osepchuk 1978). This demonstrates the fast drop of power density with increasing distance from the oven.…”

“…Most microwave ovens operate at 2450 MHz with operating power ranging from 0.5 to 2 kW; industrial type ovens operating at higher power are also available (Osepchuk 1978, Gandhi 1990). The US code of federal regulation (CFR) 21 part 1030 specifies the maximum amount of leakage (emission) from microwave ovens at distances of 5 cm from the oven to be 1 mW cm −2 before the oven is sold and 5 mW cm −2 throughout its operating life (FDA 1992).…”

“…Some ovens were found to radiate more than the specified limit, a fact which was attributed to oven age and the lack of cleaning and proper maintenance. A thorough review of microwave oven safety, standards, nature of leakage and customer usage was conducted in the United States (Osepchuk 1978). The conclusion was that leakage from microwave ovens is less than the specified safe limit at points very close to the oven and that the EM field intensity is very low at the distance where the user usually stands.…”

Electromagnetic radiation from microwave ovens in Saudi Arabia was investigated by means of a field measurement survey. The survey was carried out for 106 ovens used in households and restaurants in Riyadh city. Ovens were between 1 month and 14 years old with operating power ranging from 0.5 to 4.4 kW. One oven was found to leak more than the 5 mW cm(-2) limit specified in the standard. Fifteen other ovens were found to leak 1 mW cm(-2) or more, with the remaining ovens leaking less than that. Based on the survey result, previous studies and the fast decay of radiated power density with distance from the oven, the conclusion was that user exposure to RF radiation from microwave ovens is much less than the general public exposure limit set by most international standards at 2450 MHz, i.e. 1 mW cm(-2), and that a detrimental effect on health is an unlikely result of exposure to radiation from microwave ovens.

“…The design of the oven has an important impact on the efficiency, as it affects the electric field distribution inside the cavity [ 21 – 24 ]. Avoiding the power leakage, which mainly occurs through the door, has been a key issue [ 25 , 26 ], and that is why special attention has been paid to the design of the oven door [ 27 – 30 ]. Typically, the leakage has been treated as interference for devices like pacemakers [ 31 ] and wireless communication systems (Wifi, ZigBee, and Bluetooth), as the microwave oven operates in the ISM (industrial, scientific, and medical) frequency band of 2.4 GHz [ 32 – 34 ].…”

The electromagnetic field leakage levels of nonionizing radiation from a microwave oven have been estimated within a complex indoor scenario. By employing a hybrid simulation technique, based on coupling full wave simulation with an in-house developed deterministic 3D ray launching code, estimations of the observed electric field values can be obtained for the complete indoor scenario. The microwave oven can be modeled as a time- and frequency-dependent radiating source, in which leakage, basically from the microwave oven door, is propagated along the complete indoor scenario interacting with all of the elements present in it. This method can be of aid in order to assess the impact of such devices on expected exposure levels, allowing adequate minimization strategies such as optimal location to be applied.
