Radionuclides exhibit distinct radiological properties based on their mode of decay, which can include alpha, beta, or gamma radiation. Alpha emitters tend to have low penetration power and can be stopped by a sheet of paper, while beta particles can penetrate further but are still relatively weak against materials like plastic or aluminum. Gamma rays, on the other hand, are highly penetrating electromagnetic radiation that requires dense materials like lead for effective shielding. Additionally, the half-life of radionuclides determines the duration of their radioactivity and influences their applications in fields such as medicine and energy.

What are the two radionuclides which concentrate on seafood?
Although Mercury can be found in fish and shellfish the two radionuclides which concentrate in seafood are Lead-210 and Polonium-210. (Source: FEMA Radiological Emergency Management Course IS-3)
What are the biological properties of radionuclides - slide11?
Radionuclides possess unique biological properties that significantly impact their behavior in living organisms. They can emit ionizing radiation, which can cause cellular damage, alter DNA, and lead to mutations or cancer. The type of radiation (alpha, beta, or gamma) influences their biological effects, with alpha particles being the most damaging when ingested or inhaled, while beta and gamma rays can penetrate tissues more effectively. Additionally, certain radionuclides can accumulate in specific organs or tissues, affecting their biological pathways and overall health outcomes.
Who treats diseases with radionuclides?
radiologist
What effect do radionuclides have on living things?
Radionuclides can be very hazardous to living things. It can damage the tissues and cause irreversible changes to the cells.
What are the biological properties of radionuclides?
Biological properties - 1. Radionuclides cannot be destroyed or degraded, unlike organic substances as such - a. Because radionuclides cannot be destroyed, disposal of residual radioactive wastes are usually very technical and limited. The waste forms must meet disposal site waste acceptance criteria. b. The storage is also a problem 2. They are able to be put into the body easily (injection, inhalation, ingestion) 3. They have mimic behaviour of biological material, as such they are able to be 'stuck to' a biological material for a specific test (labelling) 4. They have short physical half-life, thereby decay quickly. But long enough to be produced and delivered to the exam site
What substances used in radiology that emit radiation?
radionuclides

When was Journal of Radiological Protection created?
Journal of Radiological Protection was created in 1988.
What is the correct radiological symbol that may indicate radiological material is present on or near the scene?
radiation symbols indicating radiological material is present on or near the scene?
What is external radiological material?
Radiological material physically attached to an external surface (person)
What are the radiological properties of radionucletides?
Radionuclides are characterized by their ability to emit radiation as they decay, which can include alpha particles, beta particles, and gamma rays. The type of radiation emitted depends on the specific radionuclide, influencing its penetration power and biological effects. Alpha particles have low penetration and can be stopped by a sheet of paper, while beta particles can penetrate skin but are stopped by materials like plastic. Gamma rays, being highly penetrating electromagnetic waves, require dense materials like lead or concrete for effective shielding.
When was International Commission on Radiological Protection created?
International Commission on Radiological Protection was created in 1928.
