| The subsequent nuclear crisis caused by the tsunami has also largely left Tokyo unaffected, despite occasional spikes in radiation levels. |
|
| Heinrich Rudolf Hertz's work in the domain of electromagnetic radiation was pivotal to the development of modern telecommunication. |
|
| All the levels of the universe, the macrocosm, come about through the radiation or manifestation of God, the metacosm. |
|
| The low-level radiation released won't kill you immediately, but avoid long term exposure. |
|
| In nuclear medicine, it is used to build models of radiation transport in targeted tumor therapies. |
|
| It was later discovered that this radiation could knock hydrogen atoms out of paraffin wax. |
|
| In 1928, Walter Bothe observed that beryllium emitted a highly penetrating, electrically neutral radiation when bombarded with alpha particles. |
|
| The benefits suggested include operation in high radiation or high temperature environments. |
|
| The integrity of the right optic radiation was analysed by means of a hodologic probabilistic approach. |
|
| For this simulation, the surface-to-surface radiation model was chosen since there was not shortwave radiation, only longwave radiation. |
|
| Greenpeace had reason to suspect that recent tests had opened a crack in the atoll, causing a serious radiation leak. |
|
| Together, these data indicate that entolimod is a highly promising potential life-saving treatment for victims of radiation disasters. |
|
| At the lower end, heat transfer to the room is dominated by convection from the glass and shade and by longwave radiation transfer. |
|
| So much for the claim of radiation downplayers about the absolute risk method. |
|
| Some of the earliest bind iodine-131, an isotope that emits low-energy gamma radiation along with a beta particle. |
|
| Most hospitals stock cutie pies to monitor radiation contamination levels during an emergency. |
|
| Their innovative procedure, Epimacular Brachytherapy, utilizes highly targeted strontium 90 beta radiation in a one-time surgical procedure. |
|
| The side effects of the treatment course, which involves surgery, craniospinal radiation therapy and intensive chemotherapy, are considerable. |
|
| A numerical method is developed to find the source and direction of the coherent radiation that is responsible for the existence of attopulses. |
