Where you live

1. Cosmic radiation at sea level (from outer space) 26

2. Select the number of millirems for your elevation (in feet) up to 1000 ft.= 2 1000-2000 ft.= 5 Elevation of some U.S. cities (in feet): Atlanta, 1050; 2000-3000 ft.= 9 3000-4000 ft.= 9 Chicago, 595; Dallas, 435; Denver, 5280; Las Vegas, 4000-5000 ft.= 21 5000-6000 ft.= 29 2000; Minneapolis, 815; Pittsburg, 1200; Salt Lake 6000-7000 ft.= 40 7000-8000 ft.= 53 City, 4400; Spokane, 1890; Washington, DC, 25.

8000-9000 ft.= 70 add this number:

3. Terrestrial (from the ground):

If you live in states that border the Gulf or Atlantic Coast, add 23 If you live in the Colorado Plateau area (around Denver), add 90 If you live in middle America (rest of the U.S.), add 46

4. House construction:

If you live in a stone, brick, or concrete building, add 7

What you eat and drink

5. Internal radiation (in your body):*

From food and water 40 From air (radon) 200

Other sources

6. Weapons test fallout (less than 1):** 1

7. Jet plane travel:

For each 1,000 miles you travel, add 1

8. If you have porcelain crowns or false teeth, add 0.07

9. If you use gas lantern mantles when camping, add 0.003

10. If you wear a luminous wristwatch (LCD), add 0.006

11. If you use luggage inspection at airports (using typicalx-ray machine), add 0.002

12. If you watch TV**, add 1

14. If you have a smoke detector, add 0.008

15. If you wear a plutonium-powered cardiac pacemaker, add 100

16. If you have had medical exposures:*

Diagnostic X-rays (e.g., upper and lower gastrointestinal, chest), add 40 If you have had nuclear medical procedures (e.g., thyroid scans), add 14

17. If you live within 50 miles of a nuclear power plant(pressurized water reactor), add 0.0009

18. If you live within 50 miles of a coal-fired electrical utility plant, add 0.03

My total annual mrems dose:

Some of the radiation sources listed in this chart result in an exposure to only part of the body. For example, false teeth result in a radiation dose to the mouth. The annual dose numbers given here represent the "effective dose" to the whole body.

• These are yearly average dose.

• • The value is actually less than 1.
