X-Ray equipments produce ionising radiation.
These can be harmful to both Patients and Doctors, if proper precautions are not followed.
X-Rays are an important diagnostic tool, when it's used in a proper way.
In India, the Atomic Energy Regulatory Board (AERB) (www.aerb.gov.in) is responsible for the regulation and proper usage of X-Rays. AERB approves X-Ray machines from radiation safety point of view. Some of the key checks done by AERB includes:
Ensuring manufacturer has the proper personnel, equipment and infrastructure to manufacture safe X-Ray equipment.
Ensuring X-Ray equipment being sold is safe from radiation point of view.
Monitoring the equipments are kept in good condition.
Make sure that correct procedures are followed.
Suggestions on proper usage
Buy only AERB approved or authorised equipment.
Ask for the radiation test certificate from the manufacturer.
Perform a quality check of your equipment every year.
Limit exposure to X-Ray - both direct or scattered.
Wear protective apron and other accessories.
Wear dose monitoring badges.
Register yourself with AERB.
Do you need a Lead Lined and Separate X-Ray Room ?
This depends on the type of X-Ray machine. As per AERB guidelines, for Dental Intra-Oral (IOPA), Handheld and Mobile type X-Ray, a separate Lead Lined room is not mandatory. However, it is mandatory that safety aprons and safety rules are followed when using these equipments.
A good X-Ray equipment is one of the requirement for a clear X-Ray.
Equal importantance is to use a good quality film.
Ensure the film has not expired.
The film will keep in a dark cool environment which away from the X-Ray room.
Procedure followed for developing the film is also very important.
The developer, fixer and water are to be used as per instructions.
Replace with fresh solution at least once in two weeks.
Too cold or too warm solution should not be used.
Ensure the dark room does not have any brightness.
When using Digital Sensor, ensure it is properly calibrated and serviced.
Digital Sensors degrade over time; take note to replace worn out sensors.
The imaging software will have various options for image adjustments.
Calibrate the sensor/film with the X-Ray machine.
Each sensor/film works best for a particular exposure parameter.
Imaging techniques are very important to get the right image.
Position the film as close as possible to the object to be imaged.
Keep the sensor/film perpendicular to the X-Ray cone.
During exposure, the patient should remain steady to avoid blurred image.
Comparison between Dental X-Rays
Important note: The comparitive table below is relative. It assumes that all three type of X-Rays have passed relevant safety and performance tests. For example, the term "HIGHER" or "LOWER" does not make the equipment better or worse than the basic safety and performance requirements.
