Yet that's not what the scientists saw in their experiments at the ISOLDE radioactive beam facility at CERN, Europe's particle physics laboratory near Geneva.
However, the radium treatment of cancer was not put on to a scientific basis until the 1920's, when radium needles and radon seeds, (radium emanation sealed into glass tubes), were used as implants--accurate methods of dosage now having been developed together with the treatment of deeper cancers by radioactive beam therapy from 'radium bombs'.
A highly radioactive beam was emitted from a protective flask as it was driven 130 miles and it was "pure good fortune" that no one was dangerously contaminated when a plug was left off a 2.5-tonne container carrying radioactive material on a lorry, Leeds Crown Court heard.
A HIGHLY radioactive beam was emitted from a protective flask as it was driven 130 miles across northern England, a court heard yesterday.
Over the last 15 years, there has been a gradual transition from accelerators of stable heavy ions to radioactive beam facilities.
Each artifact was placed under special X-ray equipment that delivered a nondestructive radioactive beam, enabling the researchers to calculate the amounts of certain trace elements in the basalt.
Irradiation works by zapping infected plants or food with radioactive beams, killing bacteria, and is also used to induce genetic variation in plants.
The 63 papers cover methods for producing light exotic nuclei and nuclear structure; the synthesis and properties of superheavy elements; rare processes and decays in nuclear reactions; production and research programs, nuclear reactions, and structure of radioactive beams; experimental set-ups and future projects; and scientific projects.
