Note Please not to place any other objects within the movable range of the components of the product.
4. Radiation protection
X-ray is harmful for the health. The wrong understanding and operation will cause radiation injuries on the patients, the operator and other persons.
The operator shall receive the training on the radiation protection with corresponding protection knowledge and attention should be paid to the followings:
Note Notes on radiation protection:
☆ The overexposure will not only impact the image quality but cause the radiation injuries as well. Therefore, it’s quite important to select reasonable exposure parameter and dose.
☆ Unnecessary exposure or wrong operation will cause radiation injuries on the patients, the operator and other persons.
☆ The operator should make sure the patient in reasonable posture and use the facilities to prevent or reduce the radiation injury to the patient, making sure the safety of the patient.
☆ The distance between the focus and the skin of the patient shall be kept as far as possible to make sure the absorption dose as low and reasonable as possible.
☆ Adequate measures should be taken to protect the patient, medical staff and other persons from direct exposure of X-ray in any conditions.
☆ Attention should be paid to the secondary radiation protection as stray radiation.
☆ The operator shall pay attention to the individual dose monitoring and regular physical examination.
☆ The product room should meet the related requirements of the national and local environment protection and health and quarantine sectors, to make sure no radiation injuries on the operator and other persons.
☆ No alteration should be made on the radiation protection circuit of the product without the prior content of the Company.
Maximum permissible dose (MPD) of the operator
Many studies have made the foundation for MPD of X-ray, of which achievements have been used in the development of MPD standards by International Commission on Radiological Protection (ICRP). Such restraints are not easy to determine and shall be applicable after tracking the latest achievements from time to time. At present, ICRP stipulates that MPD for the radiation staff shall not exceed the following requirements:
Stochastic effect
Annual dose equivalent 50mSv (5rem)
Non-stochastic effect
Annual dose equivalent for eye crystal 150mSv (15rem)
Annual dose equivalent for other parts 500mSv (50rem)
Stray radiation protection
Any objects in the path of X-ray shall cause secondary (scattering) radiation, whose strength depends on the energy and strength of the original radiation and the atomic numbers of the irradiated objects. The strength of the second radiation may be stronger than that of the radiation reaching the front screen of the image intensifier. Therefore, measures should be taken to protect people from the secondary radiation.
It's an effective measure to reduce the danger to the minimum to use the lead shield, as well as lead gloves, apron and neckerchief for thyroid. The lead shield must be not less than 0.5mm thick or 0.5mm equivalent and personal protection appliance as apron and gloves must be not less than 0.25mm thick or 0.25mm equivalent. Please refer to the basic radiation protection standards provided by the radiation protection sector for the basic protection requirements.
Individual dose monitoring
The individual dose monitoring is made to provide the reliable data to make sure whether the inspected is under a safe radiation dose. It can indicate the incorrect or improper actual radiation protection measures and some positions with radiation leakage. It’s the most effective method to measure the exposure quantity with the devices in the exposure to determine whether the protection measure is applicable. Such devices should be placed at all positions possible for the operator or body parts to expose and the measured block shall not exceed the acceptable dose standards.
A common but not accurate method to determine the exposure quantity is to place the film on the typical positions and develop it after a period to determine the radiation quantity.
The generally used method to test the overexposure under the radiation is the individual dosimeter, where the film or substance sensible to X-ray is sealed and placed on the body. However, such method can only be used to measure the radiation reaching to the wearing part. It still can provide reliable measurement on the radiation dose reaching to the body.
