Fun Radiation Calculator on APC
#11
We didn't have a calculator in the sixties. They told us the box in the back was a " tissue equivalent ionization chamber." We knew who the human tissue simulators were -- us in the pressure suit.
Project Cold Flare:
Description and results of a project designed to measure solar proton and galactic background radiations at SST cruising altitudes [70,000], using RB-57F aircraft flying over routes at high geomagnetic latitudes [North Pole] are given. A radiation measuring device called the High Altitude Radiation Instrument System (HARIS) was designed, built, and flown in these aircraft during alert/scramble missions. The HARIS included a linear energy transfer spectrometer, a tissue equivalent ionization chamber, and a Geiger-- Muller tube, with data recorded on a digital magnetic tape recorder. A Concorde in-flight radiation warning device was also used in some of the flights. Solar proton radiation measurements showed maximum readings on absorbed dose rate of 1.0 mrad/hr and a dose equivalent rate of 2.0 mrem/hr.Cosmic background radiation data averaged 0.45 mrad/hr and 0.9 mrem/hr, respectively.(IAA)

Bummer, I got 44 micros yesterday. The company is required to keep track of it for us. We have a company limit of 4 point something in a rolling 12 months before they start looking to reduce us. The absolute limit is (I think) 6.48 millisieverts for a rolling 12 month period.

As soon as they get sued by a family who's career pilot spouse/parent died from skin cancer they'll start taking action. But until then it's wasted funds that could be spent on a GBU-24, or more likely a Plasma screen in the CC's office!

Sad but true..
Gushubble:
Yeah, when I went through RTU they warned us to not use use the self-protection pod (ALQ-131) or radar within 15 ft of personnel or fuel trucks/explosives/etc.
It wasn't until much later that I thought "Wait a minute...this radar has a beam of 1.5 degrees---this is really concentrated even out to a long distance!!"
I found it laughable in my last fighter squadron that we couldn't use Liquid Paper, also known as "whiteout," for correcting paperwork. OSHA had declared it hazardous. (fumes of some sort).
Yet I could fly with 2-5,000 lbs of high explosive strapped to the jet, no further than 15 ft from my seat.
I had visions of the Bomb Dump bunkers being re-labelled as "Office Supplies."
