Microwave ovens are fantastically quick, easy to use and convenient, and we couldn’t imagine life without them. New under-counter and over-range microwaves make life in the kitchen even easier, but they do pose some potential dangers. They expose parts of the body to radiation, although in very small doses. No long-term studies have confirmed that the small amounts of radiation we’re exposed to from microwaves are safe, so here’s what you can do to minimise the dangers of microwaving.

Minimise your exposure to radiation

Exposure to high levels of radiation from microwaves can damage the eyes and cause cataracts, as well as cause temporary sterility in men. So avoid cooking directly in front of a combination range hood and microwave. Also make sure microwaves are in good working condition. If the casing or door is bent or damaged, or the microwave continues cooking with the door open, stop using it immediately.

Don’t put metal or plastic in microwaves

Keep anything metallic, like knives and spoons, tin foil and metal containers out microwaves. They can damage the oven by reflecting microwaves. Sparks and fires are also a possible danger.

Also avoid putting plastic in microwaves. There’s no official definition of the term ‘microwave-safe’ that you see on some containers, and many plastics will release a dangerous chemical called BPA when heated. BPA has been linked with neurological and developmental problems.

Additional warnings

Microwaves can pose a burn risk because they heat water past boiling point. This doesn’t generally happen if there is something in the water like coffee, stock cubes, or any other ingredient. Stick to boiling water in the kettle and on the stove, and only use the microwave to heat food and other liquids when necessary.

Cooking meat in microwaves can pose a health risk because microwaves cook food unevenly. Raw meat needs to be thoroughly heated to ensure that all harmful bacteria is killed, so if you must cook meat in the microwave, be sure it is thoroughly heated all the way through.
