The ions and electrons are quickly absorbed among the billions of gas molecules in the tube so the counter effectively resets itself in a fraction of a second, ready to detect more radiation. Geiger counters can detect alpha, beta, and gamma radiation....
1. make clear or plain, describe, demonstrate, illustrate, teach, define, solve, resolve, interpret, disclose, unfold, clarify, clear up, simplify, expound, elucidate, put into words, throw light on, explicate (formal), give the details of He explained the process to us in simple terms. ...
Why is alpha radiation more ionizing than gamma radiation? How is beta radiation produced by a radioactive isotope? How are gamma rays detected? Describe the process of producing a gamma camera images, including the preparation of the patient and how the gamma camera works. ...
44, 61 The process of macropinocytosis, used by dendritic cells to internalize soluble antigens constitutively,62 is another possibility, but we are not aware of evidence that this process can translocate 2-μm particles across the endothelial barrier. Hemorrhage is another sign of tumor vessel ...
The substances that disintegrate by the spontaneous emission of radiations are referred to as radioactive substances. Examples include uranium, radium, polonium, thorium, actinium, etc. The isotopes of nearly all elements of an atomic number higher than 82 are radioactive because in all these ...
Sexual dimorphism in dioecious plants refers to sexual differences in primary and secondary sex characteristics1,2. Such divergences between males and females are the results of sexual selection for traits that influence individual fitness during the evolution process3. Selective pressure may lead to se...
Ginseng, the root of Panax ginseng (Meyer), has been used as an herbal medicine for 2000 years and was recorded in the Chinese medical classic “Shen-Nong-Ben-Cao-Jing” [1]. According to the medical literature [1], ginseng was used to reinforce vital energy, invigorate the spleen, and...
"he managed to get the AI to float out of the box. It takes the form of a small black star that glows. The star, looking much like an asterisk "*" is surrounded by six outwardly-curved segments, and around these are two thin and punctured circle lines indicating radiation from the st...
Wilhelm Conrad Rontgen, a German physicist, developed X-rays, commonly referred to as X-radiation, in 1895. The name X-radiation describes an unknown type of radiation. X-rays can penetrate any object because of their very high frequency and energy. Because of ...
Why is a reversible adiabatic process isentropic? Why is the 2nd overtone the 3rd harmonic? Why is adaptive radiation important? Why is conservation of energy related to conservation of momentum? Why are logarithms used in Snell's law? Why electromagnetism is important? Why is electromagnetism impo...
