Definition: Relating to the protection against harmful effects of radiation.

Example: Certain substances are known to have radioprotective properties that help shield cells from radiation damage.

Definition: A substance that helps protect living tissues from the harmful effects of radiation.

Example: Scientists are researching new radioprotective agents to safeguard patients during radiation therapy.

Definition: Having a reaction or response to radiation, particularly in biological contexts.

Example: Certain types of cancer cells are radiosensitive, meaning they can be effectively treated with radiation therapy.

Definition: A device that is sent into the atmosphere, usually by a balloon, to collect and send back weather information.

Example: The scientists launched a radiosonde to measure temperature and humidity at different altitudes.

Definition: A medical procedure that uses focused radiation to treat or destroy diseased tissue, such as tumors, without the need for traditional surgery.

Example: The doctor recommended radiosurgery as a less invasive option for treating the tumor.

Definition: A method of sending data over long distances using radio waves.

Example: The scientists used radiotelemetry to track the movements of the animals in the wild.

Definition: A medical treatment that uses radiation to kill or shrink cancer cells and other diseases.

Example: The doctor recommended radiotherapy as part of the cancer treatment plan.

Definition: A type of thorium that is radioactive and has a mass number of 228.

Example: Radiothorium is used in some scientific research due to its radioactive properties.

Definition: A substance that contains a small amount of radioactive material, used in medical imaging or research to track processes in the body or other systems.

Example: The doctor used a radiotracer to help visualize the patient's organs during the scan.

Definition: A rare and radioactive metal that glows in the dark and is found in small amounts in certain minerals. It is used in medical treatments and in some types of paints that shine.

Example: Radium was once commonly used in cancer treatment before safer alternatives were discovered.

Definition: A straight line from the center of a circle to its edge, or the distance from the center to the edge of a circular area.

Example: The radius of the circle is five centimeters.
