Rays are emitted from the nuclei of unstable atoms during radioactive decay , while x - rays are from the electron cloud as the result of electron excitation 射线是由不稳定原子核射出的,而射线则由受激发的电子云射出。
From their work emerged the picture of radioactive decay that is still valid - a violently disruptive explosion of a single atom 根据他们的工作,展现出至今仍然成立的关于放射性衰变的图象- -单个原子的强烈的分裂性爆炸。
Rays are emitted from the nuclei of unstable atoms during radioactive decay , while x - rays are from the electron cloud as the result of electron excitation 射线是由不稳定原子核射出的,而射线则由受激发的电子云射出。
His work was done before the discovery of radioactivity and the understanding that natural radioactive decay provides a source of heat to the earth 他的工作是做了,才发现放射性和谅解,即天然放射性衰变提供热源,以地球。
Probably the best source for random numbers in common use is measuring radioactive decay . it s not at all easy to bias , and comes with relatively little natural bias 最后,我们将解释如何在您自己的应用程序中建立防盗自动警报,以及侵入探测的现代方法可能对您有何帮助。
Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles (ionizing radiation). There are many different types of radioactive decay (see table below).
