Radiation-induced lung injury (RILI) refers to the damage that occurs to lung tissue as a result of exposure to radiation, typically from therapeutic radiation used in the treatment of cancers located in or near the thoracic region, such as lung cancer, breast cancer, and esophageal cancer. RILI can occur as a result of radiation therapy delivering high doses of radiation to the lungs, leading to inflammation and injury. **Types of RILI:** 1.

The International Federation of Model Auto Racing (IFMAR) is a governing body that oversees and regulates the sport of model auto racing, particularly focused on radio-controlled (RC) cars. Established to promote and organize competitions at an international level, IFMAR sets the rules and standards for various classes of model racing, ensuring fair play and consistency across events. IFMAR organizes world championships and other international competitions, providing structure and support for regional and national federations involved in model auto racing.

BeetleCam is a unique camera rig designed to capture wildlife photography and videography from low angles, simulating the perspective of small animals or insects. It is typically mounted on a remote-controlled car or robot, allowing photographers to position the camera very close to the ground without disturbing the subject (often in safari or wildlife settings). This approach enables creatives to obtain dynamic shots that would be difficult to achieve with traditional equipment.

The Okumura model is a radio wave propagation model used primarily for predicting signal strength and coverage in mobile communication systems, particularly in urban environments. Developed by Takashi Okumura in the 1960s, this empirical model provides estimations for the path loss of radio signals over various environments, including urban, suburban, and rural areas.

Hilary Blumberg is an accomplished psychiatrist and researcher known for her work in the fields of psychiatry and mental health. She has contributed significantly to understanding and treating mood disorders, particularly bipolar disorder. Blumberg has been involved in research that utilizes neuroimaging techniques to study the brain and its functions in relation to mood disorders, aiming to improve diagnosis and treatment options. Her work often explores the biological and psychological components of mental health conditions to enhance the understanding of their underlying mechanisms.

The Area-to-Area Lee model is a type of spatial interaction model used in transportation planning, urban studies, and geography to understand and predict the flow of people, goods, or information between different areas or zones. It is a refinement of the earlier gravity model concepts used to analyze spatial interactions based on the principle of gravity, which states that larger areas have more interaction with other areas, and that the strength of this interactions decreases with distance.

VOACAP stands for Voice of America Coverage and Prediction. It is a computer program used for predicting radio propagation conditions for shortwave radio communications. Developed for the Voice of America (VOA), VOACAP uses various factors, including frequency, transmission power, antenna characteristics, and geographic location, to estimate the likelihood of radio signals reaching desired locations.

The ITU model for indoor radio propagation, as defined by the International Telecommunication Union (ITU), aims to predict radio signal attenuation in indoor environments. One of the more commonly referenced models is the ITU-R P.2108 recommendation, which provides guidance on the assessment of indoor propagation characteristics.

Bioremediation is a process that uses living organisms, typically microorganisms such as bacteria, fungi, or plants, to remove or neutralize contaminants from soil, water, and other environments. This technique is commonly employed for the cleanup of polluted sites, especially those affected by hazardous waste, oil spills, heavy metals, and pesticides.

The Agence nationale pour la gestion des déchets radioactifs (ANDRA) is the French National Agency for Radioactive Waste Management. It is responsible for managing the handling, storage, and disposal of radioactive waste in France. Established in 1991, ANDRA plays a central role in ensuring the safe management of radioactive waste, including the operation of disposal facilities and the research and development of sustainable solutions for waste management.

Eben Byers was an American socialite and industrialist who became notable primarily for his death in 1932, which was linked to his excessive consumption of a radium-based patent medicine called Radithor. This product was marketed as a cure-all and was promoted for its purported health benefits, including increased energy and vitality. Byers was a wealthy man and was known for his extravagant lifestyle.

The Radium Ore Revigator was a water container designed in the early 20th century that was claimed to enhance the health benefits of water through the use of radium. The Revigator was marketed as a way to bring the purported healing properties of radium to everyday drinking water. It typically consisted of a ceramic water jug lined with radium-infused materials.

A **group ring** is a mathematical structure that is used in abstract algebra, combining concepts from both group theory and ring theory. More specifically, if \( G \) is a group and \( R \) is a ring, the group ring \( R[G] \) is a new ring constructed from these two objects. ### Construction of the Group Ring 1.

Canada has several facilities dedicated to the storage and management of nuclear waste. Here are some key facilities: 1. **Nuclear Waste Management Organization (NWMO)** - While the NWMO itself isn't a storage facility, it is responsible for the long-term management of used nuclear fuel in Canada. It is currently working on plans for a deep geological repository. 2. **Used Fuel Storage Facilities**: - **Darlington Nuclear Generating Station** (Ontario) - Contains a used fuel storage facility.
