CO OZNACZA SŁOWO RADIATION
Promieniowanie
W fizyce, promieniowanie jest procesem, w którym fale elektromagnetyczne przemieszczają się przez próżnię lub media zawierające materię; istnienie medium do propagowania fal nie jest wymagane. Inna, ale powiązana definicja mówi, że promieniowanie jest podzbiorem tych fal elektromagnetycznych połączonych z klasą energetycznych cząstek subatomowych o bardzo wysokiej energii kinetycznej; nazywane są promieniowaniem jonizującym, a cząstki nazywane promieniowaniem cząstkowym. Inne rodzaje fali, takie jak akustyczne, sejsmiczne, hydrauliczne itd., Zwykle nie są uważane za formy "promieniowania" w każdym sensie. Rozważymy pierwszą definicję i powrócimy do drugiej. Słowo to wynika z fenomenu fal wychodzących ze źródła. Ten aspekt prowadzi do systemu pomiarów i jednostek fizycznych, które mają zastosowanie do wszystkich rodzajów promieniowania. Ponieważ takie promieniowanie rozrasta się podczas przechodzenia przez przestrzeń i gdy jej energia jest zachowana, moc wszystkich rodzajów promieniowania promieniującego ze źródła punktowego jest zgodna z odległością od jego źródła.
Definicja słowa radiation w słowniku
Pierwszą definicją promieniowania w słowniku jest emisja lub przenoszenie energii promieniowania w postaci cząstek, fal elektromagnetycznych, dźwięku itd. Inną definicją promieniowania są cząstki itp. Emitowane, w szczególności cząstki i promienie gamma emitowane podczas rozpadu jądrowego. Promieniowanie jest również nazywane również: radioterapia z użyciem substancji radioaktywnej.
CYTATY ZE SŁOWEM «RADIATION»
Słynne cytaty i zdania ze słowem
radiation.
Information of fundamental importance to the general problem of atomic structure has resulted from systematic studies of the cosmic radiation carried out by the Wilson cloud-chamber method.
When X-rays traverse matter of any kind, this matter becomes a source of a radiation similar in character to that of the primary radiation falling upon it.
The process of radiation may be, and is, continuous - at any rate within limits extending to far smaller quantities than the quantum.
Direction coupling between the various radiations generated in a nuclear reaction both with one another and with the initiating radiation can also be detected and measured by coincidences; this provides valuable information about the structure of the atomic nuclei.
In this case, the particle formed has correspondingly less energy, whereas the product nucleus passes into the ground state with emission of the quantity of energy saved as gamma radiation.
The material particle nature of primary cosmic radiation has been confirmed, although the processes turned out to be extraordinarily more complicated than we had assumed.
I am now almost certain that we need more radiation for better health.
My main frustration is the fear of cancer from low dose radiation, even by radiologists.
Too many radiologists still believe there is a risk from a chest x-ray. Few radiologists can explain radiation to the patient in words the patient can understand.
It is likely that we need more radiation to improve our longevity.
