Tom and Astro recognized them immediately as testing machinery for radioactivity, much more advanced and sensitive than the ordinary Geiger counter. Around the two men was ample evidence of Astro's original assumption that they were digging into a hot vein of uranium pitchblende.
"It's a question of radioactivity, then! Remember Le Bon's experiments, Sir Henry?" But Miss Clarke was sorely mystified by this simple matter, and herself repeated the experiments. Equally puzzled was Mme. Le Fabre. According to her theory, a spirit wouldn't mind a little thing like a metal box. Of them all, Dr.
If a salt of radium is heated, the emanation becomes more abundant, and the residue, which, however, does not sensibly diminish in weight, will have lost all its radioactivity, and will only recover it by degrees. Professor Rutherford, notwithstanding many different attempts, has been unable to make this emanation enter into any chemical reaction.
Rip checked the radiation level and didn’t like it a bit. He decided to set up the landing boat and their supplies as far away from the craters as possible, which was on the sun side. They could move to the dark side as they approached the orbit of earth. By then the radioactivity from the blasts would have died down considerably.
This is necessary in a cosmology which aspires at a qualitative understanding of the universe, in view of the qualities represented by these names. They are not to be considered as parts of the indigenous astral structure of our cosmic system any more than radioactivity is an original feature of the earth.
"The thought naturally occurs that the aliens were the rather decadent relics of a highly developed technological civilization existing on the planet in the not too distant past. Yet Miracastle offers no evidence for the existence of a prior technology no ruins, no residual radioactivity from atomic operations. In short, the city has no apparent genesis in the past.
Those who refuse to admit the possibility of "action at a distance," who insist on inventing a connecting material medium between every observed effect and some material object with which it seems to be in causal connection, will, I suppose, have to be allowed to exercise their ingenuity in any way to satisfy their minds, even though they may have to revise their theory with every fresh discovery in optics or radioactivity.
The phenomena of radioactivity were discovered accidentally in 1896 by the French chemist Becquerel. Many investigators immediately began working along this promising line, and two years later Madam Curie, in association with others, discovered the new element radium.
"So he is, but his intelligence is limited by the world he lives in, and while there are many marvelous things here, nobody has the slightest conception of inter-atomic force. They have never heard even of radioactivity. At the same time I don't mean that they shall go nosing about the car. I'll take care of that."
The regularity of the phenomenon is so great that it can be used to measure time: in 3985 seconds the activity is always reduced one-half. Radioactivity induced on any body which has been for a long time in presence of a salt of radium disappears more rapidly.
