Radon is an invisible tasteless odorless gas, a very subtle and hard to detect substance, so its "discovery" occurred over a period of years and the credit could go to a number of scientists. Here is a list in chronological order:
1899 - Robert Bowie Owens discovers alpha rays and a radioactive gas that he calls Thoron, which is actually what we now call Radon - at University of Nebraska, USA.
1899 - Ernest Rutherford discovers alpha rays coming from the air, but is not able to determine exactly what gas it is in the air that is producing them - McGill University, Canada
1900 - Friedrich Ernst Dorn discovers that radium gives off a radioactive gas that he calls Niton, which is actually what we now call Radon - in Germany.
1903 - Andre Louis Debierne discovers a radioactive gas that he calls Actinon, which is actually what we now call Radon - in France.
1903 - Sir William Ramsay is able to determine the atomic weight of the radioactive gas that everyone has been "discovering" and to determine its place in the Periodic Table of elements, under Xenon - University College, England.
At about this time, scientists decide to name it Radon and give it the chemical symbol Rn.
So pick your "discoverer" and his country. I would go with Ramsay and England, since I believe that we haven't really discovered something until we know what it is that we've got.
You can surf the Web and find the "discovery" credited to each of these men.

Is lead found in nature or is it synthetic?
Lead is an element and is natural, but is not often found in its pure state. It is usually found in an ore that has a lead compound and a mixture of other compounds of other metals. It is then refined to produce more pure lead metal.
What elements are there in lead dioxide?

Galena is the main lead bearing mineral.
In what geological structure is lead found?
Lead is most commonly found in mineral deposits within sedimentary rocks, such as limestone and dolomite. It can also be found in hydrothermal veins associated with igneous rocks and within certain types of metamorphic rocks. Additionally, lead can be present in mineral deposits formed in sedimentary basins.
Minerals found in Japan?
The minerals that are found in Japan include sulfur, coal, lead, limestone, and zinc. There are not very many mineral deposits in the country.
What country was lead discovered in?
It is not known what country made the discovery of lead. Some of the oldest finds of lead were found in Turkey as far back as 6400 BC. That was a string of beads. Lead has been used in the making of different types of ammunition for thousands of years.
Where can you find the mineral Galena in Mexico?
Galena (lead sulfide) is commonly found in silver-producing regions. In Mexico, the northern states of Zacatecas, Chihuahua and Durango are home to the largest mines of silver and lead found in that country, with 68% of the national production.
Where in Australia is lead found?

What can sectionalism lead to in a country?
Sectionalism can lead to separatism in a country. Sectionalism is one's loyalty to the interest of one's region of a country, rather than the whole country.
What state is lead found in?
According to Biologists, natural lead can be found in every state because it is a part of the environment. Elements of lead can be found in water, soil and air.
Is lead found pure?
Lead is rarely found in its pure form in nature. It is typically found in combination with other elements, such as lead sulfide (galena) or lead carbonate. Lead ore must be processed to extract the lead metal from these compounds.
Is lead naturally found in Montana?
Yes, several lead ores are found in Montana. Metallic lead is not found naturally anywhere in the world, it must be extracted from ore in a smelter.
