What are the uses of electromagnetic radiation? How does ionizing radiation cause radiation burns? Why do gamma rays have the most energy? Why is it called electromagnetic radiation? Why is uranium-235 used instead of uranium-238 in nuclear reactors?
which are converted into energy (think Einstein’s energy-mass equivalence) and emitted in the form of ionizing radiation (like alpha, beta and gamma radiation). Prolonged exposure to this type of radiation is harmful.
Beta radiation Particles with relatively small mass (i.e., an electron) and charge that travel centimeters to tens of meters in air depending on their energies. Most beta particles are capable of penetrating the skin and the lens of the eye. Gamma/x-ray radiation Photons are generally highly...
penetrating portraits of the Founding Fathers that we have. His supple new book,His Excellency: George Washington(Knopf; 320 pages), is another in that line, full of subtle inroads into the man Ellis calls the most notorious model of self-control in all of American history, the original ...
