Cross-sectional imaging modalities like MRI and CT provide images of the chest which are easily understood by clinicians. However, these modalities may not always be available and are expensive. Lung ultrasonography (US) has therefore become an important tool in the hands of clinicians as an extension of the clinical exam, which has been underutilized by the radiologists. Reinforcement of the ALARA principle along with the dictum of “Image gently” have resulted in increased use of modalities which do not require radiation. Hence, ultrasound, which was earlier being used mainly to confirm the presence of pleural effusion as well as evaluate it and differentiate solid from cystic masses, is now being used to evaluate the lung as well. This review highlights the utility of ultrasound of the paediatric chest. It also describes the normal and abnormal appearances of the paediatric lung on ultrasound as well as the advantages and limitations of this modality.

Objectives: This article is aimed to widely share information and discuss further about the emerging transformation theories of the traditional radiation protection concept of ALARA into some more modern proposed concepts, particularly in dentomaxillofacial radiology. Literature Review: The concept of radiation protection in the use of X-ray modalities in the medical field has developed along with the development of science over past decades. The concept of ALARA which has been widely known for a long time and is used as a basic of theory or main reference in radiation protection policies in several countries or at the international level now becomes a traditional, conservative and invalid principle to apply. There are several emerging theories which are considered to be more valid and representative to replace the ALARA principle. Conclusion: Newer concepts of radiation protection that have developed, ALADAIP, are considered to be more precise and specific to be the main principle of radiation protection at this time, especially in the field of dentomaxillofacial radiology.

Justification, optimization, and limitation are the three underlying principles of good radiation protection. This chapter considers how these principles apply in a variety of exposure situations. Risk-based application of the principles results in control methods comprising control over areas, control over people, and control over radiation sources. These are implemented through judgements based on the use of dose limits, dose constraints, and application of the ALARA principle. Potential dose levels and possible control measures appropriate to each situation are reviewed and evaluated in risk assessments prior to work being undertaken.

This study aimed to evaluate the radiation protection practices of medical doctors of surgical and interventional specialties in different healthcare sectors of Saudi Arabia. A cross-sectional study of medical doctors in Saudi Arabia who utilize radiation to perform interventional procedures and surgical operations was conducted. Data were gathered about the basic demographic background of the respondents, their daily application of radiation protection, and variations among different specialties and institutions regarding radiation protection practices. A total of 182 responses were received from different specialties, including interventional radiology (22%), interventional cardiology (16.5%), orthopedic surgery (14.8%), urology (14.3%), and diagnostic radiology (12.1%). Responses were received from different healthcare sectors, including the Ministry of Health (47%), private sector (26%), and university hospitals (18%). Only 59% of the respondents reported applying the As Low As Reasonably Achievable (ALARA) principle of radiation protection. The specialties with the highest reported lack of the ALARA principle application were orthopedic surgery (89%), urology (69%) and endoscopy (57%). The highest reported non-adherence to the ALARA principle was in the Ministry of Defense hospitals (50%), private hospitals (44%) and Ministry of Health hospitals (43%). The use of a personal dosimeter was reported by 58% of the respondents and only 42% reported having training in radiation protection. The respondents reported a lack of regular checking of x-ray machines (28%) and protection aprons (40%), non-availability of radiation protection guidelines (48%), and a lack of policies for radiation dose monitoring (27%) in their institutions. It was concluded that the compliance with radiation protection practices was variable and generally poor among different specialties and healthcare sectors in Saudi Arabia. Similar poor practices were reported in the international literature of different countries. The concerned authorities worldwide are advised to take further actions in this regard.

Objective: The null hypothesis was that there would be no change in as low as reasonably achievable (ALARA) behavior based on feedback from comments on the nuchal translucency quality review (NTQR) image submissions. Methods: A review of the Perinatal Quality Foundation Database found 206 practitioners who failed their first credential attempt and received ALARA comments as feedback. The second submissions of the same subjects were reviewed to determine if compliance with ALARA improved following written feedback. Results: Seventeen percent of all second submissions addressed ALARA. Sixty-one percent of second submissions passed, however only 18.4 % of those addressed ALARA. Among those who submitted thermal index at bone values on both first and second submissions, the mean values on the second submission were 0.20 lower compared to the first submission ( P = .0288). Second submission mean thermal index at bone values were 0.68 lower among those submissions with ALARA concerns addressed compared to those not addressing these concerns ( P < .001). Conclusions: Written feedback without consequences on the ALARA principle did not improve compliance.

The paper focuses on application of the ALARA principle to minimize the collective doses (both for NPP personnel and the public) related to admission of personnel to the containment for accident management activities and depending on operation of ventilation systems. Results from assessment of radiation consequences are applied to a smallbreak LOCA with failure of LPIS at VVER-1000 reactors. The public doses are evaluated using up-to-date RODOS, MACCS and HotSpot software for assessment of radiation consequences. The personnel doses are evaluated with MicroShield and InterRAS codes. The time function and optimal value of the collective dose are defined. The developed approach can be applied for minimization of the collective dose for optimization of accident management strategies at NPPs.
