Prohibition of X-ray below 100 mA operation

In 1993, WHO reviewed and set specifications under the World Health Imaging System for Radiography (WHIS-RAD).
WHO's guidelines emphasize radiation safety and adequate tube current for image quality and reduced radiation exposure.
Local Radiation Protection Survey and Evaluation revealed that some facilities exceeded guidance dose levels set by the Philippine Department of Health (DOH).

Dental, veterinary, industrial, anti-crime, and research radiographic x-ray machines are exempted if their use conforms to their licensed purposes.
Mobile C-arm units and specialized x-ray equipment such as mammography, bone densitometry, and lithotripsy devices are not affected by this circular.

New license to operate (LTO) applications for x-ray facilities using radiographic machines below 100 mA tube current will not be accepted.
Facilities previously licensed using machines below 100 mA were given until December 31, 2014, to upgrade their equipment to at least 100 mA.
Renewals of affected LTOs issued for 2014 will only be valid until December 31, 2014.
Applications for renewal of LTOs for 2015 and onwards will be rejected unless the equipment is upgraded accordingly.

Facilities operating prohibited machines beyond the December 31, 2014 deadline will face sanctions under the Implementing Rules and Regulations of Republic Act No. 9711.

The Circular took effect immediately upon issuance.
The FDA's Center for Device Regulation, Radiation Health, and Research (CDRRHR), along with Regional Field Offices, are responsible for enforcement.

Emphasis on radiation protection standards based on international best practices.
Licensing as a control mechanism for compliance with safety standards.
Time-bound phase-out for non-compliant machines to ensure public health and safety.
Coordination between national health agencies and regulatory bodies for effective regulation of medical devices.
