=__Isotope and Radioactivity__= = = =Name of radioactive isotope/electromagnetic radiation/scientist:= = = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)=
 * 1) Microwaves were discovered accidentally by Percy Spencer in the 1940's
 * 2) Microwaves heat food quickly but do not bake like conventional ovens
 * 3) The first microwave in the world was 1.8 meters(5.9) feet tall,weighed about 750 lbs and costed about 5000 us dollars each
 * 4) The original name was electro ovens then changed to microwave ovens and now mostly called microwaves
 * 5) in 1986 roughly 25% of households had microwaves and its changed to 90%

=3 Advantages of using the radioactive isotope/radiation/benefits of discovery=

1.Heats food faster so you dont have to wait for big conventional ovens to warm up and cook the food.

2.Conventional methods of cooking use energy to heat oil, water or air - microwave ovens only heat the food, so you can save on your energy bills

3.food heated quickly in a microwave retains more nutrients than foods kept hot for a long time, such as those simmered on a stove.

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1.microwaves bounce off the walls of the oven and get sent into the food but sometimes it dosent get all around the object therefor leaving cold spots.

2.May not penetrate through thick foods like meat or poultry

3.If you stand by a microwave oven too much you can receive cancer

FUN FACT:Did you know that the microwave works when the water particles meet the electromagnetic fields causing the water particles to possess the fields heating up the food quickly:) =Is the radioactive isotope/radiation/discovery still used today? Explain= Yes,its used more than ever. When it was invented people coulden't afford it but now mostly all households have a mircrowave to make life easy
