Want this question answered?
Becquerel in 1896 hadn't the possibility to identify the radiations emitted from uranium.
A safe reactor don't emit a significant or dangerous quantity of any radiation. But in the core of the reactor all the types of nuclear radiations are emitted.
Thermal radiation is emitted by the red hot heating element.
As your teacher..............
a hot-air heating system
In fact, radiations are reflected by earth but not emitted.
Becquerel in 1896 hadn't the possibility to identify the radiations emitted from uranium.
Uranium is not used for the radiations emitted.
Fission fragments, neutrons, gamma radiations; and all the radiations emitted by these fission fragments.
Radium and polonium are principally alpha emitters.
Radioisotopes are identified by the halflife, type of radiations emitted, energy of these radiations, spectrometry (mass, gamma, alpha), etc.
they are longer than those emitted by the sun.
This depends on the amount, specific activity, chemical form, type of emitted radiations.
Yes, it is. It absorbs most of the harmful radiations.
alpha radiations travel with different speed depending upon the source they are emitted from
This depends on the amount, specific activity, chemical form, type of emitted radiations.
Protactinium-231 emit alpha particles, gamma radiations, X-rays.
