Notes from John Heys G3BDQ – Radiation

As a ‘follow up’ to William’s piece in VS titled ‘Fog’ I would like to mention that during the 1939/45 war we had a 10cm H²S Radar dish with its waveguide mounted on a beach. Dodgy H²S sets from our Halifax bombers were hopefully repaired and “air tested” on the dish antenna (it rotated) and it was in action many hours a day each week.  We didn’t normally wear lead waistcoats, just normal blue battledress or overalls so no doubt suffered a fair  bit of exposure to 5 kW pulses from the dish. On night duty it was normal to obtain rations (sausages usually) and we cooked them one at a time by hanging them on a string to face the waveguide exit.  They cooked beautifully in about 2 minutes. This was my first experience with microwave cooking!  No one came to any harm at the time, no headaches or other complaints.

The word radiation conjures up all kinds of horrors to some members of the general public – they link it to atomic radiation. The house next door to me was on the market recently. A lady looking over the place with a view to purchase said as soon as she entered the place, “If you have mobile phones could you switch them off please as I am allergic to radiation.”
The viewing proceeded with the prospective purchaser going upstairs. On the landing by the rear window she saw my antenna wires and mast.

“What’s that?” she asked. When told it was a radio ham’s aerial she shrieked and said, “A radio ham moved in next door to me recently and that’s why I want to leave. I would be ill if I was so close to radiation.”

On her way out she had to walk past a computer which was switched on. “oh my God!” she said, “a computer, it’s switched on and giving off radiation. I must leave quickly.”

I normally have wire antennas with the house end coming in the shack just a few feet from my operating position. This has been my normal practice for the past 61 years and to date I never have headaches. I’ve worked all bands 2m to 136 KHz – all powers and so far “touch wood,” no problems. Is a pity I can’t cook my sausages with my antenna lead – think of the money I would save.
