They found themselves in a vast cave which was dimly lighted by the tiny grains of radium that lay scattered among the loose rocks.
Scraps turned around and found a row of girls seated in radium chairs ranged along one wall of the room.
The apartment was hewn from the material of the cliff, showing mostly dull gold in the dim light which a single minute radium illuminator in the centre of the roof diffused throughout its great dimensions.
Four men accompanied me from the chamber, and with a radium hand-light to illumine the way, escorted me through seemingly interminable tunnels, down, ever down beneath the city of Helium.
At his side hung a long-sword, a short-sword, a dagger, and one of the destructive radiumrevolvers that are common upon Mars.
Morganium is a radioactive element next in the series to radium and much more active.
Radium also gives off an emanation, and among its products is helium, quite another element.
Then there were the experiments of John Butler Burke of Cambridge, who claimed that he had developed "radiobes" in tubes of sterilised bouillon by means of radium emanations.
Curie and Madame Curie were finally led to the discovery of radium is one of the most fascinating chapters in the history of science.
And according to the new theory of matter, not only radium atoms, but the atoms of all the other elements (hitherto regarded as irreducible) are composed of electrons, differently grouped.
The radiumatom is infinitely more unstable than the atoms of the other elements; but it is possible to conceive of the disintegration of these also.
That substance, wherever it occurs, is undergoing a continual process of disintegration; radium atoms are continually breaking up into more elementary bodies.
It continually evaporates (the life of radium is only 2500 years) but it is as continually renewed by the infinitely slower disintegration of uranium.
Were it not for the fact that radium itself is the product of the disintegration of another element, it would be impossible to account for its survival.
The particles into which theradium atom disintegrates are known as electrons.
He was the first to call attention to the probability that radium plays a part in the maintenance of solar heat.
It is believed that the subatomic energy in a mass of radium is at least a million-fold greater than the energy represented in the combustion or other chemical transformation of any ordinary substance having the same mass.
Boltwood made a report on the life of radium which may he regarded as a study of inorganic evolution.
These, if confirmed, would show thatradium alone has practically no effect on cultures of tubercle or colon bacilli; that 0.
In view of the fact that emanations of the radium as well as the combinations of the evasive iodin terpins enter into the organism through the lung.
Since then the Dioradin Company has submitted two reports of examinations of Dioradin made for the company in Germany showing a higher radium content than that previously found.
In the rocket were installed radium repulsion rays which swerved all approaching meteors from the path of the rocket as they entered the vicinity of the space wanderer.
They are using radium repellent rays to keep us from approaching," he informed.
Would the satellite follow its orbit to the world's end, or would its supply of radium soon exhaust itself after so many eons of time, converting the rocket into the prey of the first large meteor which chanced that way?
Imagine being four miles inside of the earth exposed to radium "ore"!
If I remember my science right, ultra-violet light would make the radium on the dial glow; and the lead in the tin-foil of the tobacco wrapping would screen it off.
Also, I would imagine that it wouldn't be safe to handle a chunk of radium like the characters in the story did; it's liable to burn.
Radium for instance, or rather some products of its disintegration, are thought to take on the characters of Helium and of Lead.
However, at present it seems unlikely that it will ever be possible to produce more than half an ounce of radium a year.
It would almost seem as if some method of enlarging the earth, or of arranging voyages to the moon and Mars, would be necessary in order to give the new radium machinery sufficient scope for its activities.
In conjunction with Professor Debierne she treated a decegramme of bromide of radium by electrolytic process, getting an amalgam from which was extracted the metallic radium by distillation.
Radium banks have been established in London, Paris and New York.
A solid salt of radium develops such an amount of heat that to every single gram there is an emission of one hundred calories per hour, in other words, radium can melt its weight in ice in the time of one hour.
Radium destroys the germinative power of seeds and retards the growth of certain forms of life, such as larvae, so that they do not pass into the chrysalis and insect stages of development, but remain in the state of larvae.
Curie, is just as active as radium when first extracted from the pitchblende but its energy soon lessens and finally it becomes inert, hence there has been little experimenting or investigation.
Any material when placed near radium becomes radio-active and retains such activity for a considerable time after being removed.
It gives off but little light, its luminosity being largely due to the stimulation of the impurities in the radium by the powerful but invisible radium rays.
As a result of its emission of heat radium has always a temperature higher by several degrees than its surroundings.
Radium stimulates powerfully various mineral and chemical substances near which it is placed.
This suggestion has been experimentally confirmed, the growth of radium in large quantities of a solution of purified uranyl nitrate having been observed.
It should be noted that up to the middle of the year 1910 the element radium itself had not been prepared; in all the experiments carried out radium salts were employed (i.
We must now more fully consider the radium emanation--a substance with more astounding properties than even the radiumcompounds themselves.
But I think Greiffenhagen's recent work on the effects of radium upon ligneous tissue does rather carry out my idea that emanations from quap have rapid rotting effect upon woody fibre.
It has been said that what radium is to chemistry, the internal secretions are to physiology.
Then when we have gone about five hundred miles, give us the radium push.
It is radium we have to have to make the return trip.
This question has been settled by Professor Dewar, at the Royal Institution, London, by placing the radium in a medium next to the coldest that art has yet produced--liquid air.
Up to the time when radium was discovered, the most careful investigations of all conceivable sources of supply had shown only one which could possibly be of long duration.
Under these circumstances, the radium still gives out heat, boiling away the liquid air until the latter has entirely disappeared.
Definite, immediate proof of the presence of radium there is not forthcoming yet, but that presence is far more than probable, especially since the existence of solar uranium, the known ancestor of radium, has been demonstrated.
Radium was discovered only a few years ago and is still very scarce, but the results for science and life are already tremendous because scientific methods were applied in the understanding and use of it.
Radium in decomposing follows the same law; the rate of decrease at any instant being proportional to the quantity.
The time-binding energy is a complex radiating energy somewhat like the emanations of radium and it probably also has many different subdivisions.
Let us suppose that the human time-binding capacities or energies in the organic chemistry correspond to radium in the inorganic chemistry; being of course of different dimensions and of absolutely different character.
The formula for the decomposing of radium is the same—only the exponent is negative instead of positive.
Either the X-ray or radium had caused her dermatitis and nervousness.
What is believed to be the first criminal case in which radium figures as a death-dealing agent is engaging public attention at this university town.
One of these persons must have placed an order through a confidential agent in London to purchase the radiumfrom the English Radium Corporation.
Now, it is not generally known outside scientific circles, but the fact is that in their physiological effects the X-ray and radium are quite one and the same.
Thus I found that I had recovered all but a very few milligrams of the radium that had been originally purchased in London.
Pailin was done to death by a systematic application of either X-rays or radium by a student in the university who roomed next to him.
I had the dust dissolved, by a chemist who understands that sort of thing, recrystallised, and the radium salts were extracted from the refuse.
And, in addition, the emanation fromradium is steady and constant, whereas the X-ray at best varies slightly with changing conditions of the current and vacuum in the X-ray tube.
No, not unless he can produce the agent who bought the radium for you.
Radium possesses this advantage, however, that no elaborate apparatus is necessary for its use.
No one could ever have recognised you on your flying trip to London disguised as a diamond merchant who had just learned that he could make his faulty diamonds good by applications of radium and who wanted a good stock of the stuff.
Radium A, which lived 3 minutes and begotRadium B, which lived 26.
But radium is not the most mysterious of the elements but the least so.
Sir William Crookes invented this radium light apparatus and called it a "spinthariscope," which is Greek for "spark-seer.
The luminous watch dials consist of a coating of zinc sulfide under continual bombardment by the radium projectiles.
Evidently if radium is so wasteful of its substance it cannot last forever nor could it have forever existed.
The most striking peculiarity of radium is that it is always a little warmer than its surroundings, no matter how warm these may be.
If it were more it would scorch our skins, for radium is an element in eruption.
Yet now we can all afford a bit of radium to light up our watch dials in the dark.
It appears from the above that half of the radium in any given specimen will be transformed in about 2000 years.
This mental inertia of science lasted through the eighties before showing signs of breaking up; and nothing short of radium fairly wakened men to the fact, long since evident, that force was inexhaustible.
The appearance of radium robbed this argument of its cogency.
Moreover, the hard gem itself was pitted as though the passage of time had taken effect upon it, though this may have been caused by other agencies, such as the action of the radium rays.
Also radium has an indefinite life, but that is a mineral.
The crystal coffins were still there, for Bastin flashed his torch and we saw them, but the boxes of radium had gone.
A person who can go to sleep in a glass coffin kept warm by a pocketful of radium together with very accurate maps of the constellations at the time he wakes up, can, I imagine, do most things.
Then an explanation seemed to strike him and he added, "Not magic but radium or something of the sort.
Carefully she opened the hinged door in the front of the radium holder, stepped to the switch, threw off the electric light, and came to sit beside me.
I’d like to have you see radium bring out the second letter, that was underneath the first.
Again and again it persisted, and with it came the thought that the waves from the radium were the chain which bound us.
Tom went back into the other room and brought another sample of radium and used that.
At Mrs. Hartnell’s house in Washington, in the time which elapsed between the closing of the radium case and the turning on of the lights.
If you will wait I will get someradium from my laboratory and show the hidden message to you.
Somehow the radium brought out the stuff that had been apparently removed.
The letter was placed open as before, with the radium in its leaden case before it.
We can adjust the machine so that it will register anything from a wireless telegraph message through a radium discharge to the enormously powerful waves which ‘the man’ uses.
Then you haven’t taken the radium from the safe at all?
Tom is just going to have his assistant test the radium he is to use to-night, and has half a dozen reflectoscopes here,” and she waved her hand at the bench before her, where half a dozen similar instruments were placed.
Well, Denckel means to measure waves of that kind, and waves that would come from an arc lamp or a dynamo or a piece of radium or anything like that.
That’s what I want theradium for,” I said in ending.
