Such a clause would eliminate 99.999%+ of potential tenants: Almost everyone has a cell phone, and also a microwave oven, and all of these things deliberately transmit electromagnetic radiation.

(And then we have the countless unintentional radiators to contend with.)

It also rules out people who use any form of light in their household... including candles.

But I do believe the author was jokingly referencing landlords adding generic catch-all clauses without understanding the issue, and understood it went to such lengths, and found that funny. (I did)

You don't even need a light. The tenant themselves would emit lots of infrared radiation. Not to mention the black body radiation from any other items on the property that are hotter than absolute zero.

these rules aren't there to rule you out, they want you to pay their mortgage after all. the rule is to get rid of you by terminating the contract if you cause more headaches than your rent money is worth.
