| 单词 | beta particle |
| 例句 | Tritium gives off only low-energy beta particles believed to pose minimal risks for marine life and humans. Despite opposition, Japan may soon dump Fukushima wastewater into the Pacific 2023-01-23T05:00:00Z The most common are protons, neutrons, alpha particles, beta particles, positrons, and gamma rays, as shown in Figure 21.4. Chemistry 2019-02-14T00:00:00Z Because tritium emits only low-energy beta particles, it poses a modest health risk. Japan plans to release Fukushima's contaminated water into the ocean 2021-04-13T04:00:00Z The new drug contains radium 223, which targets bone and emits alpha particles that are far more massive and energetic than the beta particles emitted by older radioimmunotherapies like strontium. Well: New Radiation Therapy Prolongs Prostate Cancer Survival 2013-07-17T21:25:13Z Plus, beta particles are small enough to travel far in the body, causing damage far and wide. Radioactive Fish Near Fukushima Suggest Ongoing Contamination 2012-10-28T20:17:09.527Z Or the water could be used to make concrete, from which tritium’s beta particles are unable to escape. Despite opposition, Japan may soon dump Fukushima wastewater into the Pacific 2023-01-23T05:00:00Z For example, alpha and beta particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. Chemistry 2019-02-14T00:00:00Z In order to become more stable, the nucleus of an actinide element undergoes radioactive decay, releasing gamma rays, alpha particles, beta particles, or neutrons. The Disappearing Actinides, and Other Frustrations from the Bottom Row of the Periodic Table of the Elements 2012-01-27T18:45:02.817Z The Nuclear Regulatory Commission says that tritium emits a weak form of radiation, a low-energy beta particle similar to an electron. Radioactive tritium found in river near Vermont Yankee plant 2011-08-18T18:40:52Z The other intermediate elements, whose formation is due to the loss of beta particles only, show no decrease in atomic weight. A Brief Account of Radio-activity They are much larger than beta particles, and have less penetrative power. The Breath of Life Alpha particles can be stopped by very thin shielding but have much stronger ionizing potential than beta particles, X-rays, and γ-rays. Chemistry 2019-02-14T00:00:00Z The beta particles emanating from radium were soon identified with the electrons of the cathode ray. Occult Chemistry Clairvoyant Observations on the Chemical Elements The alpha particle, carrying a positive electrical charge, pulls electrons from the atoms through which it passes, while negatively charged beta particles can push electrons out of neutral atoms. Worldwide Effects of Nuclear War: Some Perspectives One beta particle is then lost and UX2 belonging to the fifth group is formed. A Brief Account of Radio-activity With the loss of one more beta particle the new element returns to the sixth group from which the transformation began. A Brief Account of Radio-activity The beta particle has only about one seven-thousandth the mass of the alpha particle, but its velocity is very much greater, as much as eight-tenths the velocity of light. Worldwide Effects of Nuclear War: Some Perspectives As a result, beta particles can penetrate far more deeply into bodily tissue and external doses of beta radiation represent a significantly greater threat than the slower, heavier alpha particles. Worldwide Effects of Nuclear War: Some Perspectives Beta--Another form of radioactive decay is the emission of a beta particle, or electron. Worldwide Effects of Nuclear War: Some Perspectives |
