Dubious 1980's in-home nuclear reactor ad from Japan

Back in the carefree but confusing days of the 1980's, chicks and dudes were looking for all kinds of new ways to lessen their need for oil-based energy. If you believe anything you see in this ad mockup (and that's a big "if"), a company in Japan was working on a tiny, in-home nuclear reactor -- pleasantly named Chernobyl. We'll have to assume for the moment that this was pre-catastrophic meltdown, when the Russian power-plant was considered a feat of modern engineering instead of just a big, mutant-making hellride. The device supposedly would have been "simple to operate, even for children and the elderly", but carried an ominous warning to "discontinue use" if you experience "dizziness or a tingling sensation". Was this for real? Read the translation and judge for yourself.
