Without irreparable injury to ourselves we cannot attempt to eradicate it or extirpate it. The study of atomic energy, the discovery of radioactivity, and the recognition of potential and latent energies stored in inanimate matter, throw a brilliant illumination upon the whole problem of sex and the inner energies of mankind.
Rick explained on the way back to the farm. "There are four main kinds of radioactivity. They're called alpha, beta, gamma, and neutrons. Our sample has alpha and gamma. That means it doesn't come from either bomb debris or from a reactor, because fission takes place in both, and there is almost always beta activity as well as gamma in the products of fission.
"Reactor's still too hot. Temperature and radioactivity both too high; radioactivity's still up around eight hundred REM's." "Well, then, we'll give them all the written portion of the test together, and start the personal interviews and oral tests as soon as they're through." He turned to Doris Rives. "Can you give all of them the written test together?" he asked.
She's probably drifted away from the radioactivity already." "Corbett's right," said Connel. "A hot cloud would be a hundred miles away by now." He pressed down on the acceleration lever and the jet boat eased toward the ship. Edging cautiously toward the stern of the spaceship, they saw the blasted section of the fin already cooling in the intense cold of outer space.
Better to let the Russians hold what advantage their invasion has given them than to have our cities destroyed, our population wiped out, our descendants if any born with six heads or a dozen arms as a result of radioactivity." According to General Thario, for a while it was touchandgo whether the President would yield to the men of vision or the others.
These negative results are, on the other hand, so many successes for the partisans of the explanation of radioactivity by atomic energy.
M. and Madame Curie discovered as early as 1899 that every substance placed in the neighbourhood of radium, itself acquired a radioactivity which persisted for several hours after the removal of the radium. This induced radioactivity seems to be carried to other bodies by the intermediary of a gas.
Madame Curie and M. Schmidt, independently of each other, made systematic researches in order to solve the question; various compounds of nearly all the simple bodies at present known were thus passed in review, and it was established that radioactivity was particularly perceptible in the compounds of uranium and thorium, and that it was an atomic property linked to the matter endowed with it, and following it in all its combinations.
But, of course, that was no use. He couldn't say that he didn't see Mars from a safe altitude of two thousand feet: The vast, empty deserts where, fairly safe from the present dominant form of Martian life, a few adventurers and archeologists still rummaged among the rust heaps of climate control and other machines, and among the blasted debris of glazed ceramic cities still faintly tainted with radioactivity where the original inhabitants had died.
But now the facts and principles brought to light in connection with the studies of radioactivity have settled it that we actually do have a much smaller unit than the hydrogen atom, one of only about 1/1760 its mass, in fact; and that this smallest of the small things of nature is none other than a particle of negative electricity, now called an electron.
