Creation
The microwave was patented by Raytheon. Percy Spencer of Raytheon discovered a chocolate bar melted in his pocket during his work with radar sets. He then experimented with corn and an egg realizing he could cook foods. Then he put a electromagnetic generator in a metal box to make the experiment safe, and therefore created the first microwave on accident todayifoundout.com/index.php/2011/08/the-microwave-oven-was-invented-by-accident-by-a-man-who-was-orphaned-and-never-finished-grammar-school/ -
Production of the First Microwave, The Radarange
For people to use Perry Spencer's invention, the engineer's had improve it to be able to use by everyone. Therefore the Engineers at Raytheon started to work and improve the microwave to create the Radarange. However, it was 5 1/2 feet tall, 750 pounds, and $5000. However, due to the price, it was mostly commercial. It had a water-cooled magnetron. *Exact date not given

Radiation Control for Health and Safety Act
It was passed because of the results from radiation tests through experimentation by the U.S. Department of Health, Education, and Welfare, which said the microwave ovens leaked microwaves. http://www.encyclopedia.com/topic/microwave_oven.aspx -
The Change of Microwave Ovens for Safety
Due to the Radiation Control for Health and Safety Act, the standards and regulations were published by the government, so companies got to work to abide by these regulations.
