Radiation user licence – renewals and variations

You can check your registration details and expiry date on the national registers of practitioners. Make sure your contact details provided to AHPRA, including email, are current as you will be sent reminders when your registration is due. If you do not renew your registration by 31 December end of the one month late period , your registration will lapse in accordance with the National Law and your name will be removed from the national register. If you wish to keep practising and do not renew registration by 31 December, you must submit a fast track application for registration. If submitting a fast track application, you cannot practise until your application is processed and your registration details are updated on the national register.

Advanced Search. The purpose of this program is to: inform and educate the public about services offered through the RESEP program; disseminate information on radiogenic diseases and the importance of early detection; screen eligible individuals for cancer and other radiogenic diseases; provide appropriate referrals for medical treatment; and facilitate putative applicants in the documentation of Radiation Exposure Compensation Act RECA claims. The following entities are eligible to apply for the funds described in this notice of funding opportunity:.

Additionally, only the entities located in the high-impact states cited in the Radiation Exposure Compensation Act 42 U. Individuals eligible for RECA compensation are categorized by the context in which they were placed at risk of exposure to radiation. Part 79, and in 28 CFR part see below footnote for more in-depth descriptions and definitions. In general, these categories include:. Use our track application tool.

Radiometric dating

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.

The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.

Ionizing radiation is produced by radioactive decay, nuclear fission, and fusion, by extremely hot objects, and by particle accelerators. The emission of ionizing.

This chapter presents a brief introduction to radioisotopes, sources and types of radiation, applications, effects, and occupational protection. The natural and artificial sources of radiations are discussed with special reference to natural radioactive decay series and artificial radioisotopes. Applications have played significant role in improving the quality of human life.

The application of radioisotopes in tracing, radiography, food preservation and sterilization, eradication of insects and pests, medical diagnosis and therapy, and new variety of crops in agricultural field is briefly described. Radiation interacts with matter to produce excitation and ionization of an atom or molecule; as a result physical and biological effects are produced. These effects and mechanisms are discussed.

Dating Rocks and Fossils Using Geologic Methods

All data generated or analysed during this study are included in this published article. Ionizing radiation has cytotoxic and genotoxic effects caused mainly by the oxidative damage induced by free radical release. The need for radioprotectives is increasing to protect normal tissues during radiotherapy. In the present study, we investigated the radioprotective effect of Date syrup in rats subjected to whole body radiation at 6 Gy through biochemical, molecular and histopathological analysis.

This page has been archived and is no longer updated. Despite seeming like a relatively stable place, the Earth’s surface has changed dramatically over the past 4. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth’s surface is moving and changing.

As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils. A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved. However, by itself a fossil has little meaning unless it is placed within some context. The age of the fossil must be determined so it can be compared to other fossil species from the same time period.

Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms. For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years. By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.

However, the age of each fossil primate needs to be determined so that fossils of the same age found in different parts of the world and fossils of different ages can be compared. There are three general approaches that allow scientists to date geological materials and answer the question: “How old is this fossil? Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event.

Radioisotope: Applications, Effects, and Occupational Protection

Murray, Alexandr P. Phylogenies are usually dated by calibrating interior nodes against the fossil record. This relies on indirect methods that, in the worst case, misrepresent the fossil information. Here, we contrast such node dating with an approach that includes fossils along with the extant taxa in a Bayesian total-evidence analysis.

Acceptance into the professional program is not guaranteed and an application and interview for invited candidates is required. The program starts in the fall. Students accepted into the Radiation Therapy Program will have exposure to 2 different MRI units during their clinical education. IF a student has an implant that is not MRI compatible, they will NOT be able to participate in these rotations, however, there are alternative rotations available.

Students will complete MRI education and screening form prior to the start of their clinical practicum. If you have questions or concerns over your ability to participate in these rotations, please contact the Program Director. Deadline: January 15 at PM. Late applications, including reference submissions NMT and Therapy only , will not be considered.

Section 13 of the Radiation Safety Act requires a person who may manage, control, possess or manufacture radiation sources to obtain a source licence. Failure to hold the required licence is an offence under the Radiation Safety Act A source licence is required to be renewed. A licence is renewable up to 3 years. However, if there have been changes to the previously authorised activities since the current licence was issued, the licence is no longer eligible for renewal. In this case, the licence holder must apply for variation of the current licence.

See the next section for information. Since the first licence was granted, the licensed business may have had some changes to its business. Any proposed variation in the previously granted licence must be assessed and approved before the variation is implemented. Varied licences will inherit the expiry date of the existing licences. It is recommended that you start your application process at least 4 weeks in advance to obtain your authorisation without delays.
