Simple trick :How to know if your microwave is leaking Radiation

From home kitchens to canteens, microwaves are staple appliances that many people use completely unaware of how they work. But it may panic some users to discover that the metal boxes of radiation aren't quite as self-contained as first thought. A video has revealed a simple trick to determine if your microwave is 'leaking' using just two mobile phones - but don't worry, even if it is leaking it's unlikely to cause any harm.

The YouTube video shows that microwave ovens can leak small amounts of radiation.

By placing an phone in a microwave and calling it, the video demonstrates that signals can pass through the oven's protective casing.

The surprising results show that the casing is not a perfect Faraday cage, which use mesh to block electromagnetic wavelengths from passing through.

In the video, Physics Girl places the average frequency for microwaves at 2.45 gigahertz, while mobile phone signals are typically 1.9GHz or 0.85GHz (in the UK this is 800MHz and 1.8GHz).

By using a signal receiver, which detects a wide range of signal frequencies, the video demonstrates that small amounts of microwaves do escape from the oven when it's on, but in very low amounts which fall below safety limits.
