Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
[mass noun] Gamma rays.
- ‘Those who managed to survive - in spite of the lethal heat-blast, the colossal shockwave and the invisible effects of gamma radiation - told stories of a living nightmare.’
- ‘Survival after treatment with gamma radiation was monitored after exposure to a Cesium source emitting at a dose rate of 2.7 krad/min.’
- ‘Over the last decade, ground-based telescopes and satellite-based observatories have opened new windows on the stars across the electromagnetic spectrum, from infrared to gamma radiation.’
- ‘If, on the other hand, there is a hydrogen ion and a positron, the end result is a proton (maybe a neutron, depending on the isotope) and gamma radiation.’
- ‘Centrifuge facilities emit gamma radiation, as well as many other frequencies.’
- ‘This effect can in fact be achieved through exposure to gamma radiation, if said radiation is energetic enough.’
- ‘Intriguingly, detectors flown on satellites have reported occasional bursts of gamma radiation coming from the depths of space, and there is no universally accepted explanation for this phenomenon.’
- ‘The small, lead-shielded canisters contain pellets or a fine powder of caesium 137, which emits powerful gamma radiation with a half-life of 30 years.’
- ‘This box, designed to monitor gamma radiation, in itself contained enough strontium 90 to emit 500,000 becquerels of radioactivity.’
- ‘The peaks are the days when gamma radiation was emitted by sunspots in high concentrations.’
- ‘Extragalactic astrophysicists puzzle over the nature of fantastically energetic bursts of gamma radiation, which are now known to sometimes originate in galaxies far away from our own.’
- ‘Gamma ray bursts are poorly understood short-duration plane waves of gamma radiation which pass through the solar system at rare intervals.’
- ‘These satellites will also pick up gamma radiation emitted if nuclear weapons are being manufactured.’
- ‘Nuclear isomers are excited states that eventually decay to the ground state, mostly by gamma radiation.’
- ‘Within a decade, rockets and satellites had been launched to scan the skies for objects emitting infrared, ultraviolet, and gamma radiation.’
- ‘The property, possessed by certain nuclides, of spontaneously emitting particles of gamma radiation or of emitting radiation following orbital electron capture or spontaneous fission.’
- ‘Many nuclear reactors today are based on a nuclear fission reaction where a uranium atom absorbs a neutron and breaks into two smaller atoms and releases more neutrons, heat, and gamma radiation.’
- ‘This process is called ionization, and this capability had led to gamma radiation being termed ionizing radiation.’
- ‘The technical definition is the amount of X or gamma radiation that produces one electrostatic unit of ionic charge in one cubic centimeter of dry air at standard temperature and pressure.’
- ‘There is no safe dosage of gamma radiation inside cells.’
