The first 2020 SPR Radiation Protection Study Group meeting was held on February 3rd. Physicist Renato Dimenstein read and spoke about the Brazilian Resolution RDC No. 330, published in the Federal Official Gazette, on December 26, 2019, by the Collegiate Directorate of the National Health Surveillance Agency (ANVISA).

This is a revocation of Ordinance SVS/MS No. 453, June 1, 1998 and Resolution Anvisa/RE No. 1016, April 3, 2006, which provide basic guidelines for radiological protection in medical and dental radiodiagnosis, and on X-rays throughout the national territory. It says it applies to services under private law, legal and individuals – it gives guidelines against the use or not of ionizing radiation, both for teaching, research and human health.

“It has an interesting framework, a basic text and all the provisions. Its objective is to establish the health requirements for the organization and operation of radiology services and to regulate the control of medical, occupational and public exposures arising from the use of diagnostic or interventional radiological technologies,” said Dimenstein. Hanging on it, there are Normative Instructions (NI): for RM, US, etc. In these NIs, there is a description of what is required and reference limits. At the time, he read the resolution and used an example, that of the CT.

The RDC 330 Normative Instructions must be adopted with care in terms of performance limits of radiological systems. Some parameters suggested by the IE may differ from the literature.

The physicist stressed some excerpts, such as that of Article 3, in which the legal responsible for the institution must formally designate a professional qualified to assume responsibility for the radiological procedures of each sector of diagnostic or interventional radiology.

In addition, he clarified that it recommends that acceptance tests should be carried out right after the equipment is assembled, and characteristics informed by the manufacturer should be very similar when you test.

Among the prohibitions, Article 83 states: “The system for controlling the duration of exposure to X-rays must be of the electronic type and must not allow exposure lasting more than 5 (five) seconds, except in fluoroscopy, interventional radiology, computed tomography and extraoral dental radiology.“

Important point: Who is the professional who should use it, or apply it? “According to the SPR legal, the professional in each sector must be appointed by the institution’s technical manager,” said Dimenstein.
