There are three main groupings, or varieties: Species (i.e. wild roses), Old Garden Roses (classes in existence before 1867). And Modern Roses (classes not in existence bfore 1867).
Radon is a radioactive gas that comes from the natural radioactive decay of radium, which is a natural decay product of uranium.Scientifically, âradonâ is known to be radon-222, the most abundant isotope of the element radon.As a noble gas, radon is colorless, odorless and chemically inert and cannot be detected by human senses.cientifically, âradonâ is known to be radon-222, the most abundant isotope of the element radon.

All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas.26 Ra is the most stable isotope of radium and is the last isotope in the (4 n + 2) decay chain of uranium-238 with a half-life of over a century. Its immediate decay product is the dense radioactive noble gas radon, which is responsible for much of the danger of environmental radium.
