Radon is colourless and odourless at room temperature but as the temperature lowers, it turns orange-red because it is a noble gas i would assume it is a bad conductor of thermal energy if that is what you're asking.
What is radon radon is a gas that you cannot smell, taste or see radon forms naturally when uranium, thorium, or radium, (radioactive metals) breaks down in rocks, soil and groundwater. The basics of radon presentation national safety council well as local geologic and soil characteristics, can result in great differences in radon levels for. Characteristics: radium is a silvery-white metal it is highly radioactive and its decay product, radon gas, is also radioactive one result of radium's intense.

Properties, sources and uses of the element radon radon (rn) is a radioactive, colorless, odorless and tasteless gas that occurs naturally as the decay product of the elements radium, uranium and. The levels of radon in homes and other buildings depend on the characteristics of the rock and soil in the area as a result, radon levels vary greatly in different parts of the united states, sometimes even within neighborhoods.
Radon: radon (rn), chemical element, a heavy radioactive gas of group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium (radon was originally called radium emanation. Whytlow-gray, isolated enough of the gas to study its physical properties and named it niton (the shining one) in 1904, mache [1,2], introduced the first unit for radon activity. The average cost of a mitigation system ranges between $800 to $1,200, but it can range from about $500 to about $2,500 depending on the characteristics of the house and the choice of radon reduction methods.
