Pilots with increased exposure to radiation?

Skagway Jack

As a former Navy pilot and career professional pilot (post military) I have had the dubious honor of joining this forum as a survior of kidney cancer.  I am curious of any other professional pilots who may be members here.  Recently I read an article about the amount of radiation received by pilots and crews operating at high altitudes and particularly those flying circumpolar flights.  I have about 8000 hours of flight times roughly half of which is high altitude flight.  There was no history of Kidney cancer in my family.  Thanks in advance.
