Exercises Nuclear Chemistry

If you begin with 300.0 g of a sample of a radioisotope and have 37.5 g remaining after a period of 90 minutes, what is the half-life of the radioisotope  

Strontium-90 is a radioactive isotope that was created by atomic weapons testing during World War II. The half-life of strontium-90 is 28.8 years. The first atomic weapons test took place in New Mexico on July 16, 

What fraction of the original strontium-90 remained in the desert on July 16, 2000  

For the types of radiation given, which of the following is the correct order of increasing penetrability

We simply define radiochemistry and nuclear chemistry by the content of this book, which is primarily written for chemists. The content contains fimdamental chapters followed by those devoted to applications. Each chapter ends with a section of exercises (with answers) and literature references. An historic introduction (Ch. 1) leads to chapters on stable isotopes and isotope separation, on unstable isotopes and radioactivity, and on radionuclides in nature (Ch. 2-5). Nuclear radiation - emission, absorbance, chemical effects radiation chemistry), detection and uses - is covered in four chapters (Ch. 6-9). This is followed by several chapters on elementary particles, nuclear structure, nuclear reactions and the production of new atoms (radio-nuclides of known elements as well as the transuranium ones) in the laboratory and in cosmos (Ch. 10-17). Before the four final chapters on nuclear energy and its environmental effects (Ch. 19-22), we have inserted a chapter on radiation biology and radiation protection (Ch. 18). Chapter 18 thus ends the fimdam tal part of radiochemistry it is essential to all students who want to use radionuclides in scientific research. By this arrangement, the book is subdivided into 3 parts fundamental ladiochemistry, nuclear reactions, and applied nuclear energy. We hope that this shall satisfy teachers with differrat educational goals.

Lead - The nuclear properties of 207Pb are conducive to straightforward observation of NMR spectra. The relative paucity of data in the published literature may, therefore, be a reflection of the lack of an extensive coordination chemistry or, at a more mundane level, a consequence of the relatively low solubility of many lead compounds. 207Pb chemical shifts are extremely sensitive to solvent, so care must be exercised when drawing conclusions from spectra recorded in different solvents even the change from H20 to D20 can lead to appreciable shifts (e.g. 31 ppm for Pb(NOj)2) (Lutz and Strieker, 1971).
