The Act requires that the Secretary to the Department of Health and Human Services publish an annual report that describes the activities of the Secretary under the Act. The report must summarise all authorities issued, renewed, suspended, cancelled, varied, transferred or surrendered during that year, as well as reporting on all radiation incidents investigated and listing all prosecutions for offences in that year. Under the Act, it is an offence to conduct a radiation practice or to use a radiation source without a licence. Currently there are 13,641 ‘use licences’ and 2,664 ‘management licences’ issued in Victoria, the majority of which are held in the medical and dental sectors. The department conducted 483 inspections in the 2016–17 financial year as part of its compliance monitoring program. One improvement notice and three prohibition notices were issued. Radiation Regulations 2017 The Radiation Regulations 2007 sunset on 28 August 2017. The Radiation Regulations 2017 replace them but create a similar regulatory environment to that in which Victoria currently operates, which is already closely aligned with international and national best practice. In addition to continuing to prescribe the elements in the Radiation Regulations 2007, the main focus of the changes in the Radiation Regulations 2017 is to strengthen the security of high-consequence radioactive material and to implement changes to the occupational dose limit to the lens of the eye to reflect recent international, national and state developments. The Radiation Regulations 2017 came into operation on 27 August 2017. Regulatory framework The department has been working towards improving the regulatory framework regarding radiation in Victoria. This includes documenting both the regulatory objectives and the outcomes it aims to achieve. The framework has also included developing a stakeholder communication strategy, assessing the costs of the regulatory activities, drafting performance indicators, continuing to implement a risk management framework and assessing the risks posed by different radiation practices. Regulation of medical practices (computed tomography, linear accelerators in radiation oncology and interventional fluoroscopic apparatus) During the 2016–17 financial year the department has continued its computed tomography (CT) practice inspection program, with a view to implementing a process requiring applicants seeking authority to own CT equipment to provide, with their application for licence, evidence of compliance with certain requirements pertaining to justification before a licence is granted. 3 The department also focused on regulating linear accelerators used in radiation oncology and identified a lack of consistent external auditing of dose delivery as an area of high risk. In order to address this risk the department has developed new dosimetric auditing requirements that have been specified in a document titled Requirements for independent dosimetric auditing of linear accelerators, available on the department website at <https://www2.health.vic.gov.au/about/publications/policiesandguidelines/ requirements-independent-dosimetric-auditing-linear-accelerators>. This document was developed to become a condition of licence for management licences authorising the possession of a linear accelerator for the purpose of radiation therapy. In the 2016–17 financial year, the department undertook inspections of practices involving fluoroscopic apparatus used in image-guided interventional procedures. These practices can deliver doses large enough to cause skin burns at the area of entry of the X-ray beam. The information collected through these inspections will be used to inform regulatory actions in respect of fluoroscopic apparatus in the 2017–18 financial year. Portable density/moisture gauges Inspections of radiation practices using these types of highly portable radiation sources (commonly used to measure moisture in soils, sands and so on) were completed and have resulted in a new condition of licence developed to improve the physical security of the devices. Dual-energy X-ray absorptiometry (DEXA) units These units are used to measure bone density, body fat levels and muscle mass. The department has identified an increase in the use of these units in the sports and fitness industry to determine body composition. The question for the department remains whether there is adequate medical justification for the procedure. The department continued a series of inspections of practices using these units to review the strength of justification for the use of radiation in the sports and fitness industry. Commercial tanning practices Commercial tanning practices were banned at the end of 2014. The department has taken a strong approach to enforcing the ban on commercial tanning practices through investigations of all allegations of illegal practices. During the financial year, the department continued to investigate the illegal use of commercial tanning units in Victoria with a view to prosecuting serious offenders. During the financial year, the department initiated 19 investigations, successfully completed two prosecutions, brought one case before the courts and executed 11 search warrants. Nine tanning units were seized by or forfeited to the department during search warrant actions. Mandatory testing of medical diagnostic X-ray units A prescribed radiation source may only be used for human diagnostic purposes if there is a current certificate of compliance in place. The department continued to monitor licensees for compliance with the testing requirements in 2016–17 and to monitor approved testers for compliance both with the conditions of their approval and with the provisions of the Act. A high level of compliance was observed during 2016–17. 4 Radiation Act 2005 Annual report 2016–17 Mineral sand mining and processing Mining mineral-rich sands generally requires the radiation safety aspects of the operation to be regulated

  • Radiation Shielding Design Assessment and Verification Requirements 17
    4. High-risk premises 4.1 General description 4.1.1 Premises are classified as high-risk where the potential for radiation exposure is high and substantial shielding is required to operate within dose limits. 4.1.2 A shielding plan must be prepared for all high-risk premises as detailed in Section 6 of this guideline. Complex shielding plans for high risk premises may require significantly more detail than the minimum requirements listed in Section 6. 4.1.3 There is no requirement that the shielding plan be prepared by a CRE, however, the plan must be assessed by an appropriately accredited CRE to ensure compliance with this guideline. In addition, for all premises classified as high risk, a second CRE who is appropriately accredited must carry out an independent assessment of the shielding plan to verify that the plan is satisfactory for the proposed use and that it is compliant with the requirements of this guideline. The shielding plan must be certified by the second CRE. 4.2 High-risk applications 4.2.1 Premises not classified as low or medium are considered to be high risk. These include: a. radiotherapy using a sealed source or irradiating apparatus greater than 150 kVp, including remote after-loading devices b. positron emission tomography (PET) c. in patient isolation facility for nuclear medicine therapy using unsealed gamma emitting radionuclides d. industrial radiography in fully-or partially-enclosed sites and other industrial, research and non-medical activities using radiation apparatus or using and storing sealed sources (where the activity thresholds for sealed radioactive sources, or aggregation of, are categorised as category 1, 2 or 3 as listed in Appendix A,).

  • Radiographic Sensitivity in Industrial Radiographic Testing with X-Ray Films
    Malaysia International NDT Conference & Exhibition 2015 (MINDTCE-15), Nov 22-24 - www.ndt.net/app.MINDTCE-15 Radiographic Sensitivity in Industrial Radiographic Testing With X-Ray Films By: Tee Kim-Tsew (Technical Manager, Lott Inspection Sdn. Bhd., Malaysia ASNT and ACCP Level III) Abstract. Radiographic Testing (RT) is widely used in industries, at airport for security checks, medical More Info at Open Access Database www.ndt.net/?id=18665 applications etc. to detect anomalies in materials and human bodies. Radiographic Testing is the common NDT methods used in the construction and fabrication industries for the oil & gas sectors using welding, gas/liquid transmission pipelines, casting foundries, and condition monitoring in existing oil & gas refineries and facilities. This paper will discuss radiographic testing sensitivity using industrial X-ray films mainly on welds and castings. No in-depth discussion in related science and physics, merely the perspective of an industrial radiographer based on his experience. Keywords: IQI, Quantitative, Qualitative, sensitivity, contrast, definition, geometric un-sharpness INTRODUCTION The basic principle for the detection of anomalies using radiographic testing method is the difference in radiation absorption coefficients properties exhibits by different materials. The images are captured in a recording medium. The recording medium used may be X-ray film, phosphorous imaging plates, diodes etc. Industrial X-ray films are the common recording medium used for these applications. RADIOGRAPHIC TESTING SENSITIVITY Like all other NDT methods, certain detection sensitivity is required for the technique to ensure detectability of desired anomalies. In industrial radiography, Radiographic Sensitivity is a QUALITATIVE term referring to the size of the smallest detail that can be recorded and discernible on the film/radiograph, or to the ease with which the images of small details can be recorded.

  • Industrial Radiography Exam Study Guide
    State of Georgia Industrial Radiography Certifying Exam Study Guide The questions that follow are typical calculations that are performed in the field as part of radiographic operations. They include using the inverse square law to determine shielding thicknesses, dose rates, and restricted/unrestricted area boundaries. While these are similar in nature, these questions are NOT taken from previous Industrial Radiography Certifying Exams. Please concentrate on HOW to solve the problem, not just the final answer. Additionally, a knowledge of the Radioactive Materials Rules and Regulations, Chapter 391-3-17-.04, and an understanding of safe practices in the use of radiographic equipment, is required in order to perform well on the Certifying Exam. Please prepare accordingly. Inverse Square Law The inverse square law can be represented as follows: ( 2' ( 2 I1 D1 I2 D2 where I1 = the initial dose rate (in R/hr or mR/hr), D1 = the distance from the source where I1 is measured I2 = the second dose rate; units must be the same as I1 D2 = the distance from the source where I2 is measured; units must be the same as I2 This equation can be rearranged to isolate the desired variable. Half Value Layer (HVL) The half value layer (HVL) is the thickness of a given shielding material that will reduce to dose rate by half. For example, if there is a source emitting a dose rate of 50 mR/hr, and you put a HVL of a material between yourself and the source, the dose rate on the far side of the shielding material will be reduced to 25 mR/hr.

One important industrial application utilizes various sources of ionizing radiations to investigate the integrity of structures or components through radiographic images, a practice generally re- ferred to as nondestructive radiography or industrial radiography. In- dustrial radiography to date is an established practice that provides benefits concurrent with radiation risks. The radiation protection ob- jective, therefore, is to keep the risks as low as reasonably achievable (ALARA) while maximizing benefits. Guidelines for ionizing radiation protection have been in exis- tence for more than 60 years and have been subject to numerous revi- sions in that time. One authoritative international standard-setting organization is the International Commission on Radiological Pro- tection (ICRP). In 1990, the ICRP reaffirmed its system of radiologi- cal protection aimed at reducing the radiation risks associated with ionizing radiation use, and recommended lower dose limits for radia- tion workers and the public(1). The objectives of that system with re- spect to radiation exposure are twofold: to prevent the occurrence of deterministic effects, and to reduce the incidence of stochastic ef- Published by authority of the fects.

  • European Dimension of the Implementation of the Iaea Tc Model Project "Upgrading Radiation Protection Infrastructure"
    XA0102976 IAEA.CN.84/19 EUROPEAN DIMENSION OF THE IMPLEMENTATION OF THE IAEA TC MODEL PROJECT "UPGRADING RADIATION PROTECTION INFRASTRUCTURE" J. SABOL Department of Technical Co-operation, International Atomic Energy Agency, Vienna Abstract. A comprehensive evaluation carried out by the IAEA during the period 1984—1995 showed that eleven countries in Europe — Albania, Armenia, Belarus, Bosnia and Herzegovina, Cyprus, Estonia, Georgia, Latvia, Lithuania, the Republic of Moldova, The Former Yugoslav Republic (TFYR) of Macedonia — did not have a satisfactory system for radiation protection and the safety of radiation sources in accordance with the recommended international requirements. During the past four years, these countries have been participating in a Model Project aimed at upgrading radiation protection infrastructure in the Europe region with special emphasis on the establishment of an effective legal framework for adequate regulatory control of radiation sources and facilities. This paper analyses the results accomplished in the implementation of this project. It presents the main objectives, based on the present achievements for a follow-up programme to be carried out in participating and also in some other Member States with insufficient national infrastructures for assuring adequate safety in nuclear and radiation technologies. INTRODUCTION More than 15 years ago, the IAEA systematically began to collect and analyse available information on national systems for controlling radiation sources and associated exposure involving workers, patients and members of the general public. For more than a decade, extensive data were assembled. This data reflected major weaknesses and insufficient regulatory control in more than 50 countries worldwide. These included 11 countries in Central and Eastern Europe where, for different reasons, the situation was found to be inadequate as to compliance with recognized international standards governing protection against harmful effects of ionizing radiation and the safety of radiation sources.
