Limit of dose from man-made sources to a member of the public who is not a radiation worker in the US and Canada [6] [9] 1.1 1.1 × 10 ^ 0: Annual: 0.13: Average USA radiation worker occupational dose in 1980 [6] 1.2 1.2 × 10 ^ 0: Acute-Abdominal X-ray [7] 2 2 × 10 ^ 0: Annual: 0.23: USA average medical and natural background
Commercially available medical linacs produce X-rays and electrons with an energy range from 4 MeV up to around 25 MeV. The X-rays themselves are produced by the rapid deceleration of electrons in a target material, typically a tungsten alloy, which produces an X-ray spectrum via bremsstrahlung radiation. The shape and intensity of the beam ...
Dose area product (DAP) is a quantity used in assessing the radiation risk from diagnostic X-ray radiography examinations and interventional procedures, like angiography.It is defined as the absorbed dose multiplied by the area irradiated, expressed in gray-centimetres squared (Gy·cm 2 [1] – sometimes the prefixed units dGy·cm 2, mGy·cm 2 or cGy·cm 2 are also used). [2]
dose area product (DAP) measured in gray centimeters 2; dose length product (DLP) measured in gray centimeters; rads a deprecated unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg; Roentgen a legacy unit of measurement for the exposure of X-rays; Each measure is often simply described as ‘dose’, which can lead to ...
It is worn by the person being monitored when used as a personal dosimeter, and is a record of the radiation dose received. Modern electronic personal dosimeters can give a continuous readout of cumulative dose and current dose rate, and can warn the wearer with an audible alarm when a specified dose rate or a cumulative dose is exceeded. Other ...

An early study on mice exposed to low dose of radiation daily (0.11 R per day) suggest that they may outlive control animals. [51] A study by Otsuka and collaborators found hormesis in animals. [52] Miyachi conducted a study on mice and found that a 200 mGy X-ray dose protects mice against both further X-ray exposure and ozone gas. [53]
