Three principles of radiation protection

  1. Keep as much distance as possible between yourself and the source of X-rays
  2. Keep the exposure time as short as possible.
  3. Place a shield between the source of X-rays and any people nearby.

1. Distance: Maintain a Safe Distance from the Source

Radiation intensity diminishes according to the inverse square law--doubling the distance reduces the dose to one-fourth. Establish a controlled area around the X-ray system. Use barriers, ropes, or floor markings to restrict access to authorized personnel only.

2. Time: Minimize Exposure Time

Monitoring radiation levels is essential for safety management. The following instruments are commonly used:

Survey Meters

Used to detect and measure real-time radiation levels in a specific location or around the equipment.

This is the picture of a survey meter.

Pocket Dosimeters

Worn by personnel to monitor cumulative radiation exposure over a specific period.

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 the same material, the greater the thickness, the higher the shielding effect. Lead is commonly used as a shield.

Safety Features of Matsusada Precision X-ray Systems

Our X-ray inspection systems are engineered with multiple safety layers based on radiation protection principles.

Minimized X-ray Leakage

All products feature robust lead shielding to minimize surface radiation leakage, ensuring operator safety.

Auto-off Timer

The system automatically shuts off X-ray output after a preset time (up to 60 minutes) to prevent accidental continuous exposure.

Safety Interlock System

X-ray generation is immediately cut off if the enclosure door is opened during operation.

Emergency Stop

A prominent emergency stop button allows operators to instantly halt X-ray output and stage movement in critical situations.
