Radium-223 (Ra-223) is a radioactive isotope of radium. It is part of the actinide series and is produced through the decay of uranium and thorium. Radium-223 has a half-life of about 11.43 days and emits alpha particles as it decays. Radium-223 has been studied and used in the medical field, particularly in the treatment of metastatic prostate cancer that has spread to the bones.

HobbyZone can refer to a couple of different concepts or brands, but it is most commonly recognized as a line of radio-controlled (RC) hobby products. HobbyZone is a brand under Horizon Hobby, which specializes in providing a variety of RC aircraft, cars, and accessories aimed at both beginners and experienced hobbyists. The HobbyZone line typically includes ready-to-fly (RTF) planes, which are designed for ease of use, making them suitable for novice flyers.

"Hotliner" can refer to different concepts depending on the context in which it is used: 1. **Customer Service**: In customer service, a "hotliner" may refer to a dedicated service line or hotline for urgent or priority issues, providing immediate assistance to customers or clients. 2. **Telecommunications**: The term may also relate to a specific type of phone line that is directly accessible, often used in emergency situations or special services.

Prophylactic cranial irradiation (PCI) is a preventive radiation therapy used primarily in patients with certain types of cancer, particularly small cell lung cancer (SCLC) and, in some cases, hematologic malignancies such as lymphoma and leukemia. The goal of PCI is to reduce the risk of the cancer spreading to the brain, which can occur in these types of cancers.

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.

Radiation burn, also known as radiation dermatitis or radiodermatitis, is a type of skin damage that occurs due to exposure to ionizing radiation or radiation from medical treatments, such as radiation therapy for cancer. The severity of radiation burns can vary widely depending on factors such as the dose of radiation received, the duration of exposure, the area of the body affected, and individual skin sensitivity.

Radiation proctitis is an inflammation of the rectum that occurs as a result of radiation therapy, typically used to treat cancers located in the pelvis, such as prostate, cervical, or rectal cancer. The condition can develop shortly after treatment (acute radiation proctitis) or may appear months or years later (chronic radiation proctitis).

Radioimmunotherapy (RIT) is a targeted cancer treatment that combines radiation therapy with immunotherapy. It involves the use of monoclonal antibodies that are specifically designed to bind to specific antigens on cancer cells. These antibodies are then linked to a radioactive isotope, which allows for the delivery of targeted radiation directly to the cancer cells.

Radiotherapy & Oncology is a peer-reviewed scientific journal that focuses on the field of radiation oncology. It encompasses research, clinical studies, and advances in the treatment of cancer using radiotherapy. The journal publishes articles on various aspects of radiotherapy, including techniques, technology, clinical trials, and the biological effects of radiation on cancer cells.

Radiotherapy can have various side effects on fertility, and these effects depend on several factors, including the area of the body being treated, the dosage of radiation, and the individual's age and overall health. Here’s a general overview of how radiotherapy might affect fertility in both males and females: ### In Females 1. **Ovarian Damage**: Radiation to the pelvic area can affect the ovaries, potentially leading to reduced hormone production and diminished ovarian function.

Radiopharmacology is a specialized field within pharmacology that focuses on the use of radioactive substances (radiopharmaceuticals) for diagnosis, therapy, and research in medicine. It combines principles from nuclear medicine, pharmacology, and radiochemistry to study and apply the interactions of these substances within the body.

Ridge lift is a type of lift that occurs when wind flows over a ridge, mountain, or other elevated terrain, creating ascending air currents. As the wind encounters the obstruction, it is forced upward, generating a vertical column of rising air. This phenomenon is commonly utilized in various forms of aviation, particularly by glider pilots and hang gliders, as it can provide sustained lift that allows them to gain altitude without the need for an engine.

Simple plastic airplane design typically refers to the creation of model airplanes using plastic materials, often intended for educational purposes, hobbies, or basic aerodynamics experiments. These designs can vary from simple gliders to more complex powered models and are usually characterized by their lightweight structure and ease of assembly. Here are a few key aspects of simple plastic airplane design: 1. **Materials**: The primary material used is often a type of plastic, such as polystyrene or polyethylene, which is lightweight yet sturdy.

"The Spirit of Butts' Farm" is a theatrical play produced by Peking University. It is an adaptation of an earlier play titled "The Ghost of Butts' Farm" by Richard McElvain. The story revolves around the themes of friendship, self-discovery, and the intersection of the past and present. It features a blend of humor and poignant moments, exploring the challenges and experiences of the characters who interact with the mysterious spirit associated with the farm.

Sirtex Medical Limited is a biotechnology company specializing in targeted cancer therapies. The company is known primarily for developing and commercializing a type of treatment called radioembolization, which is a minimally invasive procedure used to treat liver cancer. One of their main products is SIR-Spheres, which are tiny radioactive microspheres that are delivered directly to liver tumors through the bloodstream. These microspheres emit radiation that helps to destroy cancer cells while minimizing damage to surrounding healthy tissue.
