The purpose of this Quality Assurance (QA) protocol is to summarize guidelines that have been accepted by the majority of directors of radiocarbon dating laboratories throughout the world, and by the International Atomic Energy Agency (IAEA). Laboratories that carefully adhere to this protocol will produce consistently reliable data which will be comparable in accuracy to all other laboratories following this or any other equally rigorous quality assurance program. This statement does not, however, pertain to samples with 14C activities highly sensitive to method or degree of pretreatment, as pretreatment techniques vary among laboratories.

The purpose of this Quality Assurance (QA) protocol is to summarize guidelines that have been accepted by directors of many radiocarbon dating laboratories throughout the world, and by the International Atomic Energy Agency (IAEA). Some laboratories have followed similar procedures successfully for years. Laboratories that carefully adhere to this protocol will produce consistently reliable data that will be comparable in accuracy to all other laboratories following this or any other equally rigorous quality assurance program. This statement does not, however, pertain to samples with 14C activities highly sensitive to method or degree of pretreatment, as pretreatment techniques vary among laboratories.

As a follow-up to the meeting of experts convened at the International Atomic Energy Agency (IAEA) in February 1989, and the International 14C Workshop held in Glasgow in September 1989, the 14C Quality Assurance Program was formulated. In a joint effort of several radiocarbon teams and IAEA staff, we have prepared a set of five new intercomparison materials. These are natural materials frequently used by radiocarbon laboratories. The materials were distributed to 137 laboratories in May 1990. In February 1991, a meeting of experts was convened in Vienna to evaluate the results, to determine the radiocarbon activity of the five samples expressed in % Modern (pMC) terms and to define the 13C/12C ratio, and to make recommendations on further use of these materials. We present here the results of the exercise and the agreed consensus values for each of the five materials and discuss the different analyses that were undertaken.

The objectives of the founders of the International Atomic Energy Agency (IAEA) reflected the dual nature of atomic power: it was the embodiment of both the highest hopes and the deepest fears of mankind. First, the Agency's developmental responsibility was to accelerate the contribution of atomic energy to peace, health, and prosperity throughout the world. Second and equally important was to be the Agency's control function: to create a reliable system of safeguards against diversion of fissionable material to military uses in order that the broadening of the peaceful applications of atomic energy should not increase the danger of strengthening the military potential of nations. Within this broad framework, the Agency was to plan and carry out specific projects and activities. This responsibility was largely to be a function of the Board of Governors, whose establishment was an immediate necessity if IAEA was to begin operations.

The Israeli raid in June 1981 against the Osirak nuclear reactor in Iraq has been extensively analyzed by scholars, especially in the context of debate about the efficacy of preemptive strikes against hostile nuclear programs. Yet surprisingly, some important historical questions have been left unanswered: how did the raid affect the Reagan administration’s nuclear nonproliferation policy, and how was the raid perceived by relevant administration officials? How did the United States design its political strategy of response to the raid, and how did this strategy play out at the International Atomic Energy Agency? What does this episode tell us about Ronald Reagan’s foreign policy priorities? By exploring recently declassified documents from several archives around the world, this article addresses all of these questions and, in the process, debunks revisionist myths relating to the raid.

Background and context: In 2012, 560,000 women were diagnosed with cervical cancer (CXCA) worldwide and 266,000 women died of the disease: 86% of cases and 88% of deaths occurred in low- and middle-income countries (LMICs), and two thirds of the cases are locally advanced. For locally advanced CXCA the evidence-based treatment is a combination of external beam radiotherapy with chemotherapy and brachytherapy. Five-year overall survival for all stages combined ranges between 60%-69%, depending on the case-mix and the treatment modalities used. Countries with no access to radiotherapy may only offer palliative treatment to women diagnosed with locally advanced cervical cancer. Any curative attempt for these patients should include the two components of radiotherapy: concomitant radio-chemotherapy and brachytherapy. Radiotherapy is also a cost-effective treatment modality. Aim: To show the contribution and impact of the International Atomic Energy Agency (IAEA) to the improvement of results of CXCA in LMICs. Strategy/Tactics: Through its various programs, such as the Technical Cooperation programs, the Human Health program and the Program of Action for Cancer Therapy, the IAEA is committed to address these disproportionate geographic incidence and mortality rates introducing, expanding and improving radiotherapy services, working with partners such as WHO to improve cancer diagnosis, treatment, care, and control through collective action in these countries. Program/Policy process: During the last six decades, the IAEA has helped in addressing the growing cancer burden, delivering cancer-related assistance to LMICs, with financial and in-kind support from member states, donors and partners. The IAEA assistance has been primarily facilitated through the deployment of robust radiotherapy and nuclear medicine programs, coordinated research activities, documentation system and quality assurance program. This has enabled many member states to establish safe and effective diagnostic imaging and radiation therapy capacity to provide treatment and higher quality care to many of their cancer patients. The Program of Action for Cancer Therapy (PACT) is the IAEA's umbrella program for combating cancer and builds upon the above experience in radiation medicine expertise and technology. The WHO-IAEA Joint Program enable LMI member states to introduce, expand and improve their cancer treatment capacities and therapeutic effectiveness by integrating radiotherapy into a comprehensive national cancer control program. Outcomes: The IAEA provides tools for improving the practice of radiation medicine around the world. A fully implemented department (megavoltage and afterloading units, trained staff and quality assurance procedures in place) can treat up to 666 new CXCA cases per year, of which around 70% (466) can be cured. What was learned: Investing in radiotherapy can save lives!

Mới đây, Việt Nam đã được bầu vào Hội đồng Thống đốc Cơ quan Năng lượng Nguyên tử Quốc tế (International Atomic Energy Agency, IAEA). Kể từ khi năng lượng nguyên tử được đem vào nghiên cứu và ứng dụng thành công trong lĩnh vực cung ứng năng lượng, nó đã trở thành một tia hi vọng mới cho sự phát triển của nhân loại. Tuy nhiên, các sự kiện liên quan đến năng lượng nguyên tử, như việc ném bom hạt nhân của quân đội Mỹ vào các thành phố của Nhật Bản năm 1945 cho đến thảm họa nhà máy nguyên tử Chernobyl và Fukushima Daiichi, đã cho thấy khả năng hủy diệt của năng lượng nguyên tử. Câu hỏi được đặt ra là: Đã 10 năm kể từ khi thảm họa Fukushima xảy ra, chúng ta đã tìm ra cách giải quyết những mối lo ngại về an toàn xã hội của năng lượng nguyên tử, như rủi ro nổ nhà máy, xử lý chất phóng xạ, hay kiểm soát chế tạo vũ khí hạt nhân, với các tiến bộ khoa học công nghệ hiện nay hay chưa?Bài viết này sẽ tóm tắt bản tường trình hội nghị ‘Thorium energy for the world’ (tạm dịch: năng lượng Thorium cho toàn cầu) và bàn luận về khả năng của khoa học và công nghệ trong việc kiểm soát và phát triển ngành công nghiệp năng lượng đầy triển vọng này.
