Stefanie Russell spent £4,000 covering her house in four thick ray-repelling coats of paint and has banned mobile phones and computers.
The eccentric grandmother, from Steyning, West Sussex, even has a special device that detects unwanted signals in her home, mirror.co.uk reported.
She claims she is highly sensitive to the rays and often gets headaches and nausea as a result.
Russell believes her symptoms are so severe she cannot travel on public transport because of the number of portable devices being used.
The 72-year-old said: “I’ve not been diagnosed by a doctor but my GP surgery is aware of my condition.
“Every time I am near wi-fi or mobile phone signals I feel ill.
“It makes it difficult for me to get around and see people. I don’t touch the internet or email — it’s not safe.
“The painting inside and outside my house is nearly complete. I feel much better now I’m more protected.
“I have a device which helps me to detect how many wireless signals are near.
“I’m reassured that I will not have unwanted wi-fi guests coming into my home.
“Schools could use broadband instead of wi-fi, protecting them from early exposure to radiation.
“This is important — exposing them at an early age is essentially ‘cooking’ our children.”
