Braun had been given a relatively small container of the deadliest available radioactive material on Earth. Milligrams of it, shipped from Oak Ridge for scientific use, were encased in thick lead chests. He'd carried two hundred and fifty grams in a container he could put in his pocket. He was not only dead as he walked, under such circumstances. He was also death to those who walked near him.
Once we opened up that outer control deck to dump that tube, the whole joint started buzzing with radioactive electrons." Tom turned to the ladder leading to the control deck and disappeared through the hatch, leaving Astro and Roger alone. "What was that little bit of space gas about, Roger?" "Ah nothing," replied Roger. "Just a little argument on who was the biggest hero."
Crypton and neon, which have a density four times greater than oxygen, may, on the contrary, have partly disappeared by solution at the bottom of the sea, where it is not absurd to suppose that considerable quantities would be found liquefied at great depths. The discovery of the radioactive mineral malacone, which gives off both helium and argon, goes to support this.
The brutal impact of the man's death had driven all thought of its consequences from Brion's mind. Now he began to realize. Telt had never sent word of his discovery of the radioactive trace to the Nyjord army. He had been afraid to use the radio, and had wanted to tell Hys in person, and to show him the tape.
In fact all mineral waters and the so-called curarive muds like fango are slightly radioactive. There seems to be a little radium everywhere on earth that experiments have been made, even in the interiors of buildings. It is ubiquitous. We are surrounded and permeated by radiations that soil out there on the campus, the air of this room, all.
Yet so radioactive were her nerves, so adventurous her trust in rather vaguely conceived sweetness and light, that she was more energetic than any of the hulking young women who, with calves bulging in heavy-ribbed woolen stockings beneath decorous blue serge bloomers, thuddingly galloped across the floor of the "gym" in practise for the Blodgett Ladies' Basket-Ball Team.
Here again, the somewhat peculiar conditions made work difficult, as the instrument was very susceptible to small changes of level, such as occurred from time to time owing to the pressure of the ice on the ship. An ionium collector, for which the radioactive material was kindly supplied by Mr. F. H. Glew, was used.
To one side of the room, lead sheets lined a rough boxlike structure that Astro and Tom guessed was covering for the radioactive vein. Against the wall lay the lead-lined suits used by the miners. Further to one side, Tom saw a huge open pipe. He nudged Astro. "Look, over there," Tom whispered. "That's where the oxygen is coming from!"
Their idea was to build a radiation-detection instrument in an empty wing tank and hang the tank on an F-47. Then when a UFO was reported they would fly a search pattern in the area and try to establish whether or not a certain sector of the sky was more radioactive than other sectors. Also, they proposed to build a highly directional detector for the F- 47 and attempt actually to track a UFO.
It is allowable, however, to state that his observations are in the possession of experts in this country, who are, unfortunately, hampered in their research not only by the scarcity of the radioactive elements that we know, but also by the lack of the element or elements unknown to us that entered into the formation of the fiery ball within the cube of black crystal.
