About 150 people living or working around Japan's damaged nuclear facilities have been monitored for potential radiation exposure, and 23 have been found to be in need of treatment. How is the extent of their exposure measured? According to the United States Nuclear Regulatory Commission (NRC),...
For acute exposures, the first physical effects can be seen at around 25-50 rem, and manifests as a drop in a person’s white blood cells. Acute Radiation Syndrome occurs at 150-350 rem, presenting nausea, fatigue, hair loss, and skin reddening. The LD 30/50, which is the point wher...

What causes an isotope to be radioactive? Is radioactive decay dating reliable? In Radiometric dating, how is the starting value of a radioactive isotope determined? How does radioisotope dating work? When polonium-210 decays by alpha radiation, what isotope is formed?
Radiation is the emission and transmission of energy in the form of electromagnetic waves or particles. Radiation can be ionizing or nonionizing radiation, and only ionizing radiation has enough energy to potentially cause damage to cells and DNA. Sources of radiation include natural phenomena like ...
A burst dose of 0.75 Sv can be enough to induce radiation sickness, including nausea and a weakened immune system. Three sieverts will cause more severe effects but usually won't be fatal if you receive medical care. An instantaneous dose of 10 or more sieverts will be fatal, even with ...
Definitive delay measurements may be obtained if long‐lag bursters are truly nearby: The SNe/GRBs could emit gravitational radiation detectable by LIGO‐II if robust non‐axisymmetric bar instabilities develop during core collapse, and/or neutrino emission may be detectable as suggested by Meszaros ...
its eerie clicks signifying the presence of dangerous ionizing radiation. More recently, doctors embraced sound to indicate specific medical readings; the beep-beep of an electrocardiogram is perhaps the most iconic (unless you count Monty Python’s medical device that goesbing!). Current applications...
How can you measure the speed of light with a laser? ILasers: Lasers are highly focused beams of light. The word "laser" was originally an acronym standing for "light amplification by stimulated emission of radiation." Answer and Explanation: 1 Become a Study.com member to unlock this ans...
While some excess radiation is shed away into the lattice, most of the power remains concentrated, thus forming an extremely localized and almost stationary state. Interesting to note that in our system such self-compressing instability corresponds to a transfer of all the energy of a sequence of...
