Gamma radiation, the most powerful type of ionizing radiation, is released in high quantities during events such the detonation of a nuclear weapon. Though exposure to non-ionizing radiation is relatively much safer, side effects from short-term exposure can still cause health problems. The ...
In short, the patterns that come out of these fluctuations are very sensitive to theamountandtypeof matter and radiation both in the Universeat that time-- when it's 380,000 years old -- and alsohow it's been expandingsince. So when we analyze this data, we can learn how much matter...
The competition between two fundamental interactions determines nuclear stability. Protons and neutrons are attracted each other via the strong force. On the other hand, protons repel each other via the electric force due to their positive charge. Therefore neutrons within the nucleus act somewh...
Due to the complex nature of fundamental values, measurements of the electric and magnetic field strength are conducted using derived quantities from the fundamental units. Today, the field strengths recommended by the ICNIRP (International Commission for Non-Ionizing Radiation Protection) are recognized...
The human body is made up of several elements; these include major molecules like oxygen, carbon, hydrogen and nitrogen which serve as building blocks for macromolecules, but there are also elements found in smaller quantities called "trace elements" that What element makes protein different from ...
Their names are David Parker and Dawn Lester. And, interestingly, their backgrounds are in the field of accountancy and electrical engineering, respectively. So, that's going to be really interesting to hear their take on why they wrote this book as an engineer and an accountant. But, ...
Phosphors are usually made using a stable inert host material (typically oxides, nitrides, silicates, sulfides, or selenides) doped in small quantities with activators (such as metal or rare earth ions), which create non-homogeneities or impurities in the crystal structure enabling the emission ...
What happens in the body when you drink a poison? What are examples of criteria pollutants that are most highly toxic even in small quantities? What toxins or medications have similar actions to the organophosphates? What are the toxic effects of high doses of N...
