What are the uses and dangers of radioactive isotopes?

What are the uses and dangers of radioactive isotopes?

Radioactive isotopes can sit in the stomach and irradiate for a long time. High doses can cause sterility or mutations. Radiation can burn skin or cause cancer. Radiation can cause leukaemia and other diseases of the blood.

What are the dangers of radioisotopes?

effects: hair loss, skin burns, nausea, gastrointestinal distress, or death (Acute Radiation Syndrome). Long-term health risks include an increased cancer risk. Such risks depend upon the function of the specific radioisotope; and the route, magnitude, and duration of exposure.

What are the uses of radio isotopes?

Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies. Used in nuclear medicine for nuclear cardiology and tumor detection. Used to study bone formation and metabolism.

Are radioisotopes harmful to humans?

Radioactive isotopes, or radioisotopes, are species of chemical elements that are produced through the natural decay of atoms. Exposure to radiation generally is considered harmful to the human body, but radioisotopes are highly valuable in medicine, particularly in the diagnosis and treatment of disease.

Are radioactive tracers harmful?

Radioactive tracers used in nuclear medicine are, in most cases, injected into a vein. For some studies, they may be given by mouth. These tracers aren’t dyes or medicines, and they have no side effects. The amount of radiation a patient receives in a typical nuclear medicine scan tends to be very low.

How do radioisotopes affect the environment?

Plants and animals within the affected area take up radioactive particles, and these move through the ecosystem through bioaccumulation. Radiation pollution within waterways also accumulates within fish and other aquatic organisms, and runoff from radiation within the soil provides additional contamination.

How are radioisotopes used to study chemical reactions?

Radioactive isotopes have the same chemical properties as stable isotopes of the same element, but they emit radiation, which can be detected. If we replace one (or more) atom(s) with radioisotope(s) in a compound, we can track them by monitoring their radioactive emissions.

Why are radioisotopes unstable?

These isotopes are called radioisotopes. Their nuclei are unstable, so they break down, or decay, and emit radiation. Q: What makes the nucleus of a radioisotope unstable? A: The nucleus may be unstable because it has too many protons or an unstable ratio of protons to neutrons.

How does the radiation from radioisotopes cause damage to human tissue?

“Radiation damages cells by breaking chromosomes in DNA. This usually causes the cell to die. DNA can be repaired, but if the repair is incorrect, it could cause mutation which could lead to cancer later on”.
