n. [ NL.; meso- + thorium. ] (Chem.) a radioactive isotope of radium (radium-228) with a half-life of 5.8 years. Also called mesothorium-1 or mesothorium I to distinguish it from a subsequent decay product, mesothorium II (actinium-228). It was discovered in 1907 by Otto Hahn as a decay product of thorium (produced by decay of thorium-232). Mesothorium-1 (radium-228) in turn produces actinium-228 (mesothorium-2) as the first product of its radioactive decay, and the actinium-228 in turn decays quickly (half-life of 6 hours) to thorium-228 (which is also called radiothorium; the thorium-228 has a half-life of 1.91 years, shorter than that of the radium-228). It was discovered and named before full recognition of the nature of isotopes of the elements, and was distinguished from other variants of radium by its half-life and mode of production and decay. It was also cheaper to prepare than other short-lived radium isotopes, and was thus sold commercially, for use, e.g. in making watch dials readable in the dark by painting the hands and hour marks with a self-luminous paint containing the radioactive substance; it is therefore often referred to (e.g. in regulatory legislation) as though distinct from radium. It was one of the isotopes believed responsible for radiation-induced diseases observed in industrial workers who painted radium on watch dials in the late 1950's and early 1960's. The primary isotope of radium (radium-226) has a half-life of 1620 years, and these isotopes with shorter half-lives proved difficult to isolate and study for the purpose of finding the cause of such diseases.

, n. [ octo- eight + thorp Etymology of thorp uncertain. (ca. 1965). See quotes below. Possibly derived from octalthorpe or octotherp (once used by the Bell System?). ] A typographic symbol (#) having two vertical lines intersected by two horizontal lines. It is also called the crosshatch, hash, numeral sign and number sign; in the U. S. it is commonly called the pound sign, especially to designate the symbol as used on digital telephone dials, but this can be confusing to Europeans who think of the pound sign as the symbol for the British pound. It is commonly used as a symbol for the word number; as in #36 (meaning: number thirty-six). [ PJC ]

For the following explanation, I am indebted to Michael Quinion, whose World Wide Words web site (www.quinion.com/words) is a fascinating and invaluable resource for anyone interested in words and their origins.
Anyone who has ever used a touch-tone telephone has seen the octothorpe. It's that little tic-tac-toe symbol in the lower right corner of the keypad, right across from the asterisk (which the telco folks, in their infinite wisdom, insist on calling a "star"). According to a Bell Laboratories engineer named Ralph Carlsen, the octothorpe and asterisk keys were developed in the early 1960s and originally intended to be used only to access computer systems via a telephone line. The octothorpe symbol itself had already existed for many years, although it was usually called a "pound sign" or "number sign" because it was often used in commerce to designate weight or quantity.
According to Ralph Carlsen, a fellow Bell Labs engineer named Don MacPherson invented the term "octothorpe" when faced with the task of explaining the new touch-tone phones to corporate users. MacPherson chose "octo" (Latin for "eight") because there were eight points on the symbol.
"Thorpe" is indeed an Old Norse word meaning "village," often found in the names of English towns, but that was evidently not the source in this case. According to Carlsen, "thorpe" was chosen because at the time MacPherson was involved in a campaign pressing for the return of legendary athlete Jim Thorpe's Olympic medals from Sweden..

n. (Chem.) an earlier name for the thorium isotope thorium-228, given by its discoverer Otto Hahn. It is a radioactive substance formed as one of series of products in the chain of radioactive decay of thorium.

The name radiothorium was given prior to the full understanding of the nature of isotopes of elements. [ PJC ]
