In the gaseous (normal) state, radon is a colorless gas, as is true of all noble gases (see: xenon, krypton, neon, argon, helium). Due to its high radioactivity a radon light is impractical, but if one were constructed it would glow yellow-green.
In the solid state, things get very interesting with radon. As radon solidifies, it glows yellow, and then with decreasing temperature, glows an angry orange-red. This glow, or nightshine, comes from the Cerenkov light -- a product if radon's intense radioactivity. Needless to say, if you ever are viewing a glowing radon tube, you had best be standing behind very thick leaded glass.

Explain why radon's potential health hazard has been discovered only recently even though this gas has always been emitted from uranium-containing rocks in the ground?
Because radon has no odor or color.
What are the elements in Radon?
There are no elements in Radon, Radon is an element in its own right.
Is radon 222 an indoor particle?
Radon is a gas, possible to be in buildings. Radon 222 is an isotope of radon, the most common.
This radioactive gas sometimes seeps into and accumulates in houses?
Radon.
Is radon corrosive?
Radon is a non-corrosive gas.
What is the reactiveness of radon?
Radon is NOT reactive.
Can you smell radon?
No. Radon is odorless.
