Do not chew, break, crush or suck them as this could irritate your mouth or throat. For people who find it difficult to swallow tablets or capsules, ibuprofen is available…

Travelling to Japan It is safe to travel to Japan as radiation levels in most parts, including Tokyo, are within the normal range of background radiation. Entry to some areas…

Consequences of nonadherence include worsening condition, increased comorbid diseases, increased health care costs, and death. Nonadherence results from many causes; therefore, no easy solutions exist. What are consequences of medication…

Cosmic rays are a form of high-energy radiation that originate from outside our solar system. When they reach Earth, the rays collide with particles in the upper atmosphere to produce…

Electromagnetic shielding that blocks radio frequency (RF) electromagnetic radiation is also known as RF shielding. EMF shielding serves to minimize electromagnetic interference. The shielding can reduce the coupling of radio…

After a radiographic, fluoroscopic, CT, ultrasound, or MRI exam, no radiation remains in your body. For nuclear medicine imaging, a small amount of radiation can stay in the body for…

Because Earth's atmosphere blocks most gamma rays, observations are generally conducted by high-altitude balloons or spacecraft. In the 1960s defense satellites designed to detect X-rays and gamma rays from clandestine…

Properties of metamaterials Due to their peculiar optical capabilities (wavelength shorter than visible light), metamaterials can be invisible. So far there is nothing that is out of the ordinary, but…

Most of the uranium used in current nuclear weapons is approximately 93.5 percent enriched uranium-235. Nuclear weapons typically contain 93 percent or more plutonium-239, less than 7 percent plutonium-240, and…

β+ decay is also known as positron emission. Beta decay conserves a quantum number known as the lepton number, or the number of electrons and their associated neutrinos (other leptons…
