radioactive radiation

To walk on an area where the ground emitted radioactive radiation was to die.

They were exposed to radioactive radiation when heavy water escaped.

In 1934, Alikhanov began research on radioactivity and radioactive radiation.

Radioactive radiation does not stop at national borders.

The current of air couldn't very well blow the radioactive radiations about, since those radiations were moving too quickly and energetically to be affected.

He did several self-experiments with radioactive substances and was able to affirm the damaging effects of radioactive radiation on skin.

Radioactive radiation is not less dangerous for people, animals and crops in Europe than it is in the US.

As for types of radioactive radiation, it was found that an electric or magnetic field could split such emissions into three types of beams.

The decay energy can be calculated if the energy of radioactive radiation or the mass loss before and after radioactive decay is known.

However, it is also possible that radioactive radiations produce ions in the atmosphere by knocking electrons off atoms, and that these ions act as nuclei.

Their work on ionization of gases by collision lead to the invention of the Geiger-Müller counter, a now indispensable tool for measuring radioactive radiation.

The name niton was also suggested, from the Latin word meaning "to shine," because a sample of the gas in a glass container made the glass fluoresce through the radioactive radiations.

The long-term consequences of radioactive radiation and genetic technology have not yet been ascertained in sufficient detail, and it is impossible to estimate the effects of cloning, let alone cross-breeds.

Of the radioactive radiations, alpha rays were streams of positively charged particles, beta rays were streams of negatively charged particles, and gamma rays were waves.

Curie and Joliot showed that when lighter elements such as boron and aluminium were bombarded with α-particles, there was a continuous emission of radioactive radiations, even after the α source had been removed.
