Did the Soviet Union ban microwave ovens in 1976? Microwaves are perfectly legal in Russia and everywhere else in Europe. In fact I was not able to find a single country in the world that bans microwave ovens. They're regulated, of course, like all electric appliances; but regulation should not be mischaracterized as a ban.No, there was no such ban.here was no law that banned microwave ovens in the old Soviet Union, William Kopp made this up for his article many years ago. Several debunkers have trawled the USSR legal code without success trying to find the law-or the law that repealed it during perestroika.

Cookware used in a microwave oven is often much cooler than the food because the cookware is transparent to microwaves; the microwaves heat the food directly and the cookware is indirectly heated by the food.

A 1975 Sears Catalog Also available were microwave ovens, ranging in price from $189.95 to $439.95. Of course, there’s been a good deal of dollar inflation since 1975. Judged by changes in the consumer-price index, what $100 bought in 1975 takes about $354 to buy today. So that six-digit calculator would today cost about $49. Sears lowest-priced microwave oven in 1975 would today set you back $672. Here are some other 1975 products and their 1975 prices (along with their inflation-adjusted 2006 prices):

These wonderful contraptions had actually existed since the 1960s, but it was all a matter of cost, often prohibitive with new technological arrivals.
