Risks of Radiation - UCSF Radiology
When X-ray radiation is absorbed within our bodies, it can damage molecular structures and potentially cause harm. Very high doses of radiation can cause damage to human cells, as evidenced by skin burns, loss of hair, and increased incidence of cancer that have occurred in atomic bomb survivors.
Radiographic Testing: Safety Concerns and Alternative Methods
Potential Hazards of Radiography. The primary hazard of radiographic testing is the radiation, particularly ionized radiation. High radiation exposure can result in the following symptoms: Hair loss; Nausea; Vomiting; Hair/skin loss
Radiography is of vital importance in non-destructive testing. Radiography ensures the integrity of equipment and structures such as vessels, pipes, welded joints, castings and other devices. The integrity of this equipment affects not only the safety and quality of the products used by workers, but also the safety and quality of the

Imaging tests that use radiation, usually x-rays, are a valuable tool in diagnosis, but exposure to radiation has some risks (see also Radiation Injury). Different diagnostic tests require different amounts of radiation (see table Comparing Radiation Doses), but most of them use low doses that are generally considered safe.
Radiography Hazards and Precautions - HSE STUDY GUIDE
2023年9月18日 · Radiography Hazards and Precautions : Radiography, a non-destructive testing method used in various industries, plays a critical role in identifying defects and ensuring the integrity of materials and structures. However, it involves ionizing radiation, which can be hazardous to both workers and the public if not handled with care.
Industrial radiography can be performed in a safe manner that poses a negligible risk. However, experience also shows that emergencies and incidents involving industrial radiography sources have resulted in high doses to workers, sometimes resulting in severe health consequences such as radiation burns and in a few cases death.

Radiation may be harmful if the total accumulated dose for a person is high, as when multiple CT scans are done, because CT scans require a higher doses than most other imaging studies. Radiation exposure is also a concern in certain high-risk situations, as during the following:
New Safety Guide on Safety of Radiation Sources Used for Inspection …
2020年3月31日 · Growing security concerns globally have seen an increase in non-medical human imaging — such as screening of people to detect concealed objects, for instance prior to boarding an aircraft or when visiting a prison or to determine the presence of drugs in the bodies of suspected drug couriers.
Radiation hazards may be broadly classified as external hazards an internal hazard. External hazards occur when the source of radiation is outside the body and internal hazards arise when the source for radiation gets into the human system. Hazard evaluation is necessary in order to adopt suitable measures to control radiation exposure.
Radiation Safety in Industrial Radiography - Inspectioneering
2012年11月1日 · HSE involves ensuring the health of not only the human life working around hazardous environments, but also the environmental health that could possibly be affected... Radiographic Testing (RT) is a nondestructive examination (NDE) technique that involves the use of either x-rays or gamma rays to view the internal structure of a component.
