Alpha and beta radiation have low penetrating power and are unlikely to affect vital internal organs from outside the body. Any type of ionizing radiation can cause burns, but alpha and beta radiation can only do so if radioactive contamination or nuclear fallout is deposited on the individual's skin or clothing.
Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
Ionizing radiation is known to cause cancer in humans. [4] We know this from the Life Span Study, which followed survivors of the atomic bombing in Japan during World War 2. [5] [4] Over 100,000 individuals were followed for 50 years. [5] 1 in 10 of the cancers that formed during this time was due to radiation. [6]
Exposure to radiation causes chemical changes in gases. The least susceptible to damage are noble gases, where the major concern is the nuclear transmutation with follow-up chemical reactions of the nuclear reaction products. High-intensity ionizing radiation in air can produce a visible ionized air glow of telltale
A radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation.
I was told I had stage 4B Hodgkin’s lymphoma, a rare form of cancer that can affect people in their 20s and 30s. My response to the diagnosis was numbness—then, I felt immediately bombarded ...
Radiation-induced lung injury (RILI) is a general term for damage to the lungs as a result of exposure to ionizing radiation. [1] In general terms, such damage is divided into early inflammatory damage ( radiation pneumonitis ) and later complications of chronic scarring ( radiation fibrosis ).
