Three principles of radiation protection
- Keep as much distance as possible between yourself and the source of X-rays
- Keep the exposure time as short as possible.
- Place a shield between the source of X-rays and any people nearby.
1. Keep as much distance as possible between yourself and the source of X-rays (which are attenuated in inverse proportion to the square of the distance).
X-rays are attenuated in inverse proportion to the square of the distance. In other words, it is important for you to immediately move away when there is a risk of X-ray leakage or risk of radiation exposure. Secure an area of sufficient distance from the source of X-rays, and restrict access to only essential personnel by surrounding the system unit with rope or by placing stickers on the floor.
2. Keep the exposure time as short as possible.
A method for measuring radiation: Survey meters and pocket dosimeters are used to monitor X-ray dose.
Survey meters
Radiation dose is measured by pointing the tip of the detector toward the location you want to measure.

Pocket dosimeters
Pocket dosimeters are used by placing them in the user's pocket (in the chest/abdomen area). They indicate how much radiation an individual receives at any time.

3. Place a shield between the source of X-rays and any people nearby.
X-rays are attenuated as they pass through substances. The amount of attenuation depends on the substance. For substances of the same thickness, heavy metals with large atomic numbers have a higher shielding effect. For substances with the same specific gravity, the substance with the greater thickness has a higher shielding effect. Lead is commonly used as a shield.

X-Ray Systems from Matsusada Precision Incorporate Safety Measures Based on These Three Principles of Radiation Protection
Low leakage X-ray dose
All our products are shielded with lead.
Auto-off function
To prevent accidents due to a worker forgetting to turn off the X-rays, the X-rays are automatically stopped when the set time elapses. A time of up to 60 minutes can be set.
Interlock function
X-rays are stopped the moment the door is opened.

Emergency stop function
The X-rays and the stage are stopped simply by pressing the emergency stop button.

X-ray shielding partition
We also offer shielding partitions that are embedded with lead for protection against X-rays.
