Tube Voltage
Tube voltage refers to the amount of voltage applied to X-ray tubes. The total of radiation intensity will double in proportion to the square of the tube voltage. The wavelength of the highest strength depends on the tube voltage.
Tube Current
The current flows through X-ray tube. The total degree of intensity in X-ray tube will double in proportion to the tube current. Even with the increasing tube current, the shortest wavelength is unchanged.
Focal Spot Size
As is the case with X-ray, the flux consists of a group of rays. The value shows the size of the ray.
Geometrical magnification
If the distance from X-ray to the sample is indicated as "a" while the distance from the X-ray to the camera is "b", the geometrical magnification is given by dividing "b" by "a".
Monitor Magnification
The ratio shows the image magnification to actually display on the monitor screen. The figure contains the geometrical magnification value.
FID
FID shows the distance from the X-ray tube to the imaging camera. FID is taken to calculate the geometrical magnification. In general, the figure is not provided within the description on data sheets.
FOD
FOD shows the distance from the X-ray tube to the object. The geometrical magnification is given by dividing FID by FOD.
Leakage X-ray Dose
It is the X-ray dose leaked from X-ray device. Sv / hr (sievert per hour) is commonly used to show the figure. The unit of X-ray dose is also used in other measuring instruments including survey meters or pocket dosimeters.
Controlled Area
According to Ordinance on Prevention Ionizing Radiation Hazards issued by the Japanese government, in case of areas where the effective dose of external radiation exceeds 1.3 mSv in three months, the place is required to designate as a controlled area. If the effective dose of external radiation is within the regulatory values, you need not to regulate the place surrounding the device as a controlled area.
