- AMS viewed by an old-fashioned radiochemist

抄録
As a radiochemist, I have measured radiations emitted from radionuclides by various counting techniques : They are very useful to identify and determine most radionuclides. The techniques are, however, not useful to apply to long-lived nuclides, because decay rates decrease with the increase of half-life. In 1939,Alvarez and Cornog identified stable ^3He by using a cyclotron as a kind of mass spectrometer. This is an important contribution int he field of light nuclei studies. In the last 1970's, the AMS technique was revisited, and has widely been applied to various fields like physics, chemistry, geology, archeology, geography, etc. I gave brief comments on some long-lived nuclides which I am interested. They include ^<10>Be, ^<14>C, ^<26>Al, ^<36>Cl and ^<129>I. The last three nuclides have close connection to environmental issues such as production by nuclear weapons tests, emission from reprocessing plants, storage of nuclear waste, etc. I sincerely welcome the introduction of a new superb machine. But, we must not forget the importance of sample preparation. Accurate results cannot be obtained without careful handling of invaluable samples.
