Course Notes:

Nuclear Radiation

The following are links to web sites for natural radiation decay series.

Some Radioactive Decay Series showing half-lives. From the Uranium Information Center in Australia. Note: This is a pdf file and requires Adobe Acrobat Reader.

Natural Decay Series: Uranium, Radium and Thorium. From the Argonne National Laboratory Environmental Science Division.

Natural Radioactive Series by Yevgeniy Miretskiy. Select the decay series and the time step, then animate. This uses a bar graph to show the concentrations of the major isotopes formed in the decay series change over time. Additional data on half-lives and numbers of atoms are given on the right of the graph. Note: For long half-lives, select a longer time step.

The following are links to information on the Biological Effects of Radiation

Nuclear Radiation and Its Biological Effects. This is a link to an excerpt from the book No Immediate Danger, Prognosis for a Radioactive Earth, by Dr Rosalie Bertell

Biological Effects of Exposure to a Single Dose of Ionizing Radiation. A table summarizing the effects.

Albert Einstein's Letters to President Franklin D. Roosevelt. Leo Szilard, a Hungarian physicist who left Germany after Hitler's rise to Power, feared that Germany's nuclear scientist might be able to make a "nuclear Bomb". He had Albert Einstein sign a letter to President Roosevelt which explained the possibility of a nuclear bomb and urged that the United States not allow a potential enemy to develop it first.

How Nuclear Bombs Work. This is a link to the howstuffworks web site.

The Story of the Atomic Bomb, 1934-1945, by James Richard Fromm. This is a link to the web site. This article is well illustrated with photos of most of the people involved.

US Nuclear Tests: Nuclear tests from July 1945 to September 1992 – with web links.

Let's Make a Thermonuclear Device. In November 2001, British reporters searching through an abandoned "al-Qaida safe house" in Kabul, Afghanistan, found this document, and reported that they'd stumbled upon the terrorists' nuclear intentions. This information was published in a Nov. 15 article in the Times of London. In the article, journalist Anthony Loyd wrote that next to "physics and chemistry manuals devoted to molecular matter," he discovered this document on how to make a thermonuclear device. Marc Abrahams, a former editor of the Journal of Irreproducible Results, where the article originally appeared, said "Either there's one guy in the Taliban who had a sense of humor, or everyone was downloading everything on the Net that had the word 'thermonuclear' in it."
