They are probably right. Americium emits almost exclusively alpha particles, the nuclei of helium atoms produced by the isotope's slow decay into lighter elements. The alpha particles are so weak that they remain confined inside the victim's body. While contagion is virtually impossible, this is only slight comfort to the victims. As americium spreads through the body, it may linger in such areas as the liver, spleen and lymph system and eventually settle into the marrow of the bones. According to Pittsburgh Radiologist Niel Wald, a leading radiation specialist, the effect over a year-long period...
Enrico Clementi, a theoretical chemist at IBM's San Jose research laboratory, was familiar with the mathematical descriptions of the actions of the electrons, nuclei, atoms and molecules that participate in a chemical reaction. He was certain that a solution of all the equations involved would give a mathematically precise picture of any chemical reaction. But how could he possibly manage the hundreds of billions of forbidding mathematical steps required for the solution? To an IBM man, the answer was obvious...

...Cell Theory, formulated in 1839, states that all living matter is composed of cells, which are made up of nuclei and cytoplasm. In the last two decades scientists have found that DNA, a long double--chained molecule found in the nucleus, carries the cell's genetic information. This information is the blueprint that describes how the working parts of the cell, the proteins, should be assembled from 20 building blocks, the amino acids. Thus DNA ultimately determines the cell's function. The DNA's information is transferred to RNA (the cell's working manual), which is chemically like DNA except...
