[en] This paper describes the Virtual Classroom that is being developed, focused on Security Radiological in the field of nuclear reactors. The structure of it is analyzed, the themes treaties and pedagogical coherence between them. The audience to which it is addressed is described, in where it is housed, how to access it and how it can be used in courses of different modalities. Finally, improvements and updates are proposed to be implemented in future classroom reviews virtual.
[en] Currently, Brazil has eight inspectors in the area of nuclear medicine who participate in the licenses and authorizations for approximately 500 installations National territory. The objective of this work is to report how the regulation of nuclear medicine facilities in Brazil, both in the analysis part of site visits, including a critical review of how we can do to improve and optimize this process.

[en] Quantitative cross-sectional observational study, which evaluated radiological safety in a public hospital of first level of care in the Amazon region, between April and December 2016. The matrix of modal analysis of failures and effects, the competitive SWOT matrix, an observation guide and questionnaires validated by expert judgment. The radiology service, as well as the hospital staff, patients and companions. Inadequate conditions were found for operation of the x-ray room, under knowledge about radio protection in the operating personnel of the radiological equipment, poor perception of the risks of radiographic studies by patients and companions and the failures of greater incidence in the care process are lack of gonadal protectors, exposure errors, radiological equipment failure and improper operation of the development equipment. It is concluded that the hospital is not efficient in relation to safety radiological The radiological safety management should be reviewed and continuously improved.
[en] This work describes the development of an instrument for radiological monitoring, identified as Gamma Alarm (GAMAL01). These monitors detect the increase in intensity radiation and emit an alarm when this magnitude exceeds a certain threshold. Threshold for the emission of the alarm is fixed, so that it occurs when it is considered that the intensity of radiation may cause unacceptable exposure of personnel to radiation, in accordance with the provisions of the radiological safety regulations in force in the country. The alarm signal indicates the need to evacuate personnel from the affected site.
[en] Latin America and the Caribbean region is receiving technical cooperation assistance to have more operational Secondary Standards Dosimetry Laboratories (SSDL) within the IAEA/WHO SSDL network. There are 11 SSDL members in the region but their current capabilities do not cover the calibration demand of the region. There are only 5 SSDLs providing calibrations for radiation therapy and several clinical dosimeters are either not calibrated or calibrated abroad. Most of the SSDLs are only providing basic calibrations for radiation protection instruments but they do not have services for surface contamination meters and monitors. There are only few SSDLs providing calibrations for beta and neutron radiation and for nuclear medicine and they cannot cover the demand of the region. This paper summarizes current calibration service coverage of the region and provides few initiatives and proposals considered for increasing the calibration capabilities as well as to enhance and improve the services already provided by the SSDLs in the region
[en] The present work is developed in the UIC- ENIA Santiago de Cuba, with the objective of identifying most common radiological events, types and places where they can occur and the varied consequences of these during the work with the Troxler 3440 nuclear meter. manuals, conferences, videos and reference texts specific to the team, the expected results indicate the physical security actions of the nuclear meter to be taken into account during the execution of the work with the team, the perception of the risk for the operators and transporter of the brigade in function.
[en] The irradiators of the firm Gamma Service Medical, have many years of exploitation; Nevertheless, 20% of its components generate 80% of the problems that arise. The defects are located mainly in the solenoid, in the LEDs of a card in the control block, in two medium power transistors also from the control block, in the proximity sensors that they control the open and closed states of the shutter, in the half-life of the radiation source, in the actuator and fatigue resistance of the metal that is in the cabinet containing the source of radiation, solenoid, and proximity sensors. Of all the impairments, the most serious of The solution is the fatigue of the metal, mainly the arm that exerts a lever in the opening of the shutter
[en] This article describes the risk analysis made to the dismantling process of a self-shining irradiator of category I. Due to the characteristics of the installation, the What method was used If? The safety analysis allowed to determine the risk of potential exposures during the entire process. All the scenarios present in the process were classified, and the scenarios were identified of greater risk. The necessary security measures were established for the mitigation of consequences of these scenarios, thereby reducing the probability of occurrence, both of an accident with radiological consequences, such as an accident with labor consequences for the personnel involved in the process.
[en] The XI Regional Congress on Radiological and Nuclear Safety is held at the Havana Convention Center with debates, conferences and round tables on essential issues related to the protection of people receiving ionizing radiation by medical guidance. With the theme ''Culture of security, a shared commitment'', the Congress offers a unique opportunity to promote scientific debates among Ibero-American professionals in the areas of radiological safety.

[en] In the Integrative Work some criteria will be established that should be taken as a mechanism of evaluation of the inspection of cyclotrons in the Dominican Republic, evaluating the installation and operation of the same, with the purpose of reducing, to acceptable levels, the presence of radiations ionizing and / or radioactive materials, in order to protect the exposed persons and the environment. Currently the Dominican Republic has a cyclotron which produces radioisotopes for PET, With which positron emission tomography is performed, to diagnose diseases such as cancer, however, it does not have norms or policies that establish which are the obligations of operator, for the installation and start-up of the cyclotron.
