Answer:
The increasing order of the ability to cause harm to living tissue:
Weapons < Television tubes < Nuclear medicine < Cosmic radiation <Ground < Diagnostic X rays < Air (radon-222)
Explanation:
Here, the ability of the radiation to harm living tissue is measured in terms of millirem
Unit conversion:
\(1\ millirem = \frac{1}{1000}\ rem = 0.001\ rem\\\\or,\ 1\ rem = 1000\ millirem\)
The given radiation doses can be converted into units of millirems for comparison:
Weapons test fallout = 1 millirem
Cosmic radiation = 26 millirems
Air (radon-222) = 0.198 rems = 198 millirems
Diagnostic X rays = 0.040 rems = 40 millirems
Television tubes = 11 millirems
Nuclear medicine = 0.015 rems = 15 millirem
Ground = 33 millirems
Since a greater dosage of radiation would lead to greater risk, the increasing order of their ability to cause harm to living tissue would be:
Weapons < Television tubes < Nuclear medicine < Cosmic radiation <Ground < Diagnostic X rays < Air (radon-222)
