Quotes About Radioactivity

There were several interesting consequences of these vast explosions. They released into the global atmosphere radioactivity as great as that from two Chernobyl disasters every week for a whole year.

The discovery of slow-neutron radioactivity meant that Fermi's group had to work its way through the elements again looking for different and enhanced half-lives—which is to say, different isotopes and decay products.

10 Coal, with its ubiquitous content of uranium and thorium, releases more radioactivity into the environment when it is burned than any other fuel.

une modeste bombe atomique fait cent mille morts, sans compter tous ceux qui mourront des maladies induites par la radioactivité, des années, voire des décennies plus tard.

An objective phenomenon exists independently of human consciousness and human beliefs. Radioactivity, for example, is not a myth. Radioactive emissions occurred long before people discovered them, and they are dangerous even when people do not believe in them.

The various reasons which we have enumerated lead us to believe that the new radio-active substance contains a new element which we propose to give the name of radium.

Physicists had only recently discovered radioactivity,

And that is what radio-activity is, a quick return to the state of rest which underlies the spiritual or invisible universe.

The Islamic State has apparently gained control of several dozen kilograms of radioactive material from research institutions in Mosul, Iraq. It cannot be made into a nuclear bomb, but it could be used in a 'dirty bomb' to contaminate a wide area with radioactivity.

Madame Curie se concentró en el estudio de la medición de las sustancias radiactivas, creó un servicio de autenticación de esas medidas y definió el patrón internacional del radio, algo esencial tanto para la industria como para las aplicaciones médicas.

Each emission of an alpha or beta ray accompanies the transmutation of an atom; the energy communicated to these rays comes from inside the atom.

We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium by bombardment with alpha rays.

The Laboratory for Radioactivity consisted of only two rooms at the time; at a later date, when tests of radioactive substances became more extensive, it expanded into four rooms.

My time inside there was very short compared to the amount of time it took to take on and take off this suit and to test me for how much radioactivity I have.

In 1903, I finished my doctor's thesis and obtained the degree. At the end of the same year, the Nobel prize was awarded jointly to Becquerel, my husband and me for the discovery of radioactivity and new radioactive elements.

The first unquestionable proofs of the transformation of elements into different chemical elements have been provided by the study of the phenomena of radioactivity.

There is no doubt that radium is transformed spontaneously into an active gas, radon, emitting at the same time alpha particles, or helions.

For a long time it was assumed that anything so miraculously energetic as radioactivity must be beneficial. For years, manufacturers of toothpaste and laxatives put radioactive thorium in their products, and at least until the late 1920s the Glen Springs Hotel in the Finger Lakes region of New York (and doubtless others as well) featured with pride the therapeutic effects of its "Radioactive mineral springs." Radioactivity wasn't banned in consumer products until 1938.

There is - I will just say that there was a disastrous day where I discovered really what radioactivity is and that just because you don't see it doesn't mean that it's not everywhere, so - Yeah. I was a slow learner for sure.

Alpha particles tunnel out of uranium nuclei at the predicted rate to produce the effect known as radioactivity. Tunneling also plays an important role in the nuclear-fusion processes that make the sun shine, so life on Earth depends partially on tunneling

With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation in the laws of quantum electrodynamics.

The time necessary for the disappearance of half the atoms, called the half-life, is a fundamental characteristic of each radio-element; according to the substance, the value of the half-life varies between a fraction of a second and millions of years.

It's dark, close, cold, and intensely creepy down there. The fact that it was inhabited by things that had no love for mankind and potential radioactivity to boot didn't do much to boost its tourism industry.

RADIOACTIVITY IS A SPECIAL KIND OF ENERGY THAT COMES FROM INSIDE THE ATOMS IN CERTAIN METALS OR CHEMICALS. WHEN SOMETHING IS RADIOACTIVE, IT GIVES OFF ENERGY RAYS UNTIL THE ENERGY IS ALL GONE.
