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.
Radium-228 is more likely to cause cancer of the bone as the shorter half-life of radon-220 compared to radon-222 causes the daughter nuclides of radium-228 to deliver a greater dose of alpha radiation to the bones. It also considers the induction of several forms of cancer caused by internal exposure to radium and its daughter nuclides.
Beta particle (β) emitters such as yttrium-90 can travel considerable distances beyond the immediate tissue before depositing their energy, while alpha particles deposit their energy in 70–100 μm long tracks. [6] Alpha particles are more likely than other types of radiation to cause double-strand breaks to DNA molecules, which is one of ...
Symptoms can be made worse by the effects of surgery, chemotherapy or other drugs given to treat the cancer. [5] Improved methods of radiotherapy have reduced the exposure of non-involved tissues to radiation, concentrating the effects on the cancer.
A study of European nuclear workers exposed internally to alpha radiation from plutonium and uranium found that when relative biological effectiveness is considered to be 20, the carcinogenic potential (in terms of lung cancer) of alpha radiation appears to be consistent with that reported for doses of external gamma radiation i.e. a given dose ...
The side effects of radiotherapy on fertility are a growing concern to patients undergoing radiotherapy as cancer treatments. Radiotherapy is essential for certain cancer treatments and often is the first point of call for patients. [1] Radiation can be divided into two categories: ionising radiation (IR) and non-ionising radiation (NIR). IR is ...
