Acute radiation dose

Acute Radiation Dose refers to the amount of radiation exposure that an individual receives over a short period of time, typically less than a day. This is in contrast to a chronic radiation dose, which is received over a longer period of time. Acute radiation doses can result from various sources, including nuclear accidents, radiation therapy, and exposure to radiation sources in the environment.

Sources of Acute Radiation Dose

Acute radiation doses can occur from a variety of sources. These include:

• Nuclear accidents: These can result in significant acute radiation doses to individuals in the immediate vicinity of the accident. The Chernobyl disaster and the Fukushima Daiichi nuclear disaster are examples of such incidents.
• Radiation therapy: This is a treatment for certain types of cancer, where high doses of radiation are used to kill cancer cells. The radiation dose is typically delivered in a short period of time, resulting in an acute radiation dose.
• Radiation sources in the environment: These can include natural sources of radiation, such as radon gas, as well as man-made sources, such as nuclear power plants and medical imaging equipment.

Effects of Acute Radiation Dose

The effects of an acute radiation dose can vary depending on the amount of radiation received. These effects can range from mild symptoms, such as nausea and vomiting, to severe health effects, such as radiation sickness and death. The Acute Radiation Syndrome (ARS) is a serious illness that can occur when an individual receives a high dose of radiation over a short period of time.

Measurement of Acute Radiation Dose

The measurement of an acute radiation dose is typically done using a device called a dosimeter. This device measures the amount of radiation that an individual has been exposed to. The unit of measurement for radiation dose is the sievert (Sv), which takes into account the type of radiation and the sensitivity of different tissues to radiation.

Protection from Acute Radiation Dose

Protection from acute radiation doses involves a combination of measures, including the use of radiation protection equipment, maintaining distance from radiation sources, and limiting the time spent in areas with high levels of radiation. Template:Radiation-stub
