heh, yes. I know about RF exposure and the debates - that's why I asked the initial question. And yes, our Health Canada has their Safety Code 6 and that confuses the heck out of me.
As for the foredeck, or more relevantly the cockpit crew since the mast is more fore than aft, that was a good idea to check. The manual claims a 'vertical beam width' of '30', which I take to mean 30 degrees and I must assume that's 30degrees down from the horizontal, which means at 20' above the deck, it will hit the deck height about 34.65' away from the mast. Considering the boat is 26' long, then I expect we're safe. Even a 6' man standing on the transom won't be able to reach the RF beam so looks like my crew and I will be safe.
Now for those around the boat, I don't know how to calculate the exposure so your idea of using an online exposure calculator is fantastic. This one ( Results - Power Density Calculator
) claims the following safe distances...
Controlled environment: 8.5 - 10.5ft
Uncontrolled environment: 12 - 23.4ft
(variation occurs given the 1kW to 1.5kW potential output as well as the ground-reflection included or excluded)
If we make the leap that the site is accurate, that means that only somebody flying over my deck fore&aft or rafted to my boat and up the mast will be in danger.
I think once we factor in the amount of time exposed to a pulse radar, then that makes me feel even more comfortable using it, if necessary, in closer quarters.
I'll go check some other calculators to see if I get different results.
