Many radioactive isotopes are dangerous if not working with precautions. In some cases radiation can be used to treat diseased organs or tumours.

If we replace one or more atoms with radioisotopes in a compound we can track them by monitoring their radioactive emissions.
. Describe the problems associated with the use of radioactive. The major disadvantage of radioisotopes is well they are radioactive. Scientists have long known that radiation can cause cancer in humans.
Even in the spaceeven in the bananas which you eat everydaybut it is very less amount Mainly when we talk about the radioactivity we consider kind of ionizing Radiations 1Alpha Rays - its helium nuclei. If we replace one or more atoms with radioisotopes in a compound we can track them by monitoring their radioactive emissions. Radioactive isotopes have the same chemical properties as stable isotopes of the same element but they emit radiation which can be detected.
This is why you see strange mutations in animals and humans exposed to large amounts of radiation. Breathing in radioisotopes can damage DNA. They are radioactive That means that sooner or.
They ingested radon paint and some became ill with cancer. The particles and energy thrown off of the radioactive atoms can break chemical bonds and cause abnormal bonds to form. This type of compound is called a radioactive tracer or radioactive label.
1A3 the learners could discuss the uses of radioactive isotopes with their teacher and identify at least two problems with these uses. One example of a diagnostic application is using radioactive iodine-131 to test for thyroid activity Figure 114. Radioactive isotopes have the same chemical properties as stable isotopes of the same element but they emit radiation which can be detected.
The radioactive decay process for each radioisotope is unique and is measured with a time period called a half-life. Radioactive isotopes have numerous medical applicationsdiagnosing and treating illnesses and diseases. The process of shedding the radiation is called radioactive decay.
Radioactive isotopes can sit in the stomach and irradiate for a long time. Identify the problems associated with the use of radioactive isotopes. Radiation can burn skin or cause cancer.
A disintegrating atom emits a beta particle an alpha particle a gamma or x- ray or some combination. Radioactive iodine can build up and cause cancer. One half-life is the time it takes for half of the unstable atoms to.
Five Nobel Laureates have been closely involved with the use of radioactive tracers in medicine. Since every element has radioisotopes that means that essentially all elements have some isotopes that have the same problem. To detect problems within a body organ doctors use radiopharmaceuticals or radioactive drugs.
Radioactivity is present everywhere in the environment. Many radioactive isotopes are dangerous if not working with precautions. The thyroid gland in the neck is one of the few places in the body with a significant concentration of iodine.
-Describe the dangers and uses of radioactive isotopes. Radioactive energy waves are so small that they can pass through the body and harm a persons genetic make up found in their DNA. Gamma rays also can be an internal hazard if we breathe or eat gamma-emitting radioactive materials or if the radioactive material is introduce through an open wound but the damage they do to cells inside our bodies is not as severe as that done by alpha and beta particles.
High doses can cause sterility or mutations. Determine the atomic number and name the isotope. The radium on watch dials was incorporated in paint.
Uncontrolled exposure can harm living organisms by damaging molecules like DNA. High doses can cause sterility or mutations. In most cases these short-lived radioisotopes decay to stable elements within minutes hours or days.
This could alternatively be presented in the form of a table. Tabulate information to justify and describe the precautions taken to reduce the risk associated with the use of the chosen radioisotopes on society and the environment. Use available evidence to analyse benefits and problems associated with the use of.
The radiation it emits can cause bone cancer over long periods of time. Can diagnosis diseases using radioactive tracers. Answer 1 of 8.
Answer 1 of 3. The number of neutrons is N 6. Practice Problem An isotope has a mass number of A 11.
What are the problems associated with the use of radioactive isotopes. Z A - N 11 - 6 5 Using the periodic table we see that the element with the atomic number of 5 is boron. Agent InformationRadioisotopes are unstable chemicals whose radioactivity is measured by the number of atoms disintegrating per unit time.
29 rows radioactive isotope also called radioisotope radionuclide or radioactive nuclide any. Radioactive isotopes have numerous medical applicationsdiagnosing and treating illness and diseases. Workers used to paint the watch dials by hand and some would even lick their paint brushes to make a sharper tip.
The thyroid bones heart liver and many other organs can be easily imaged and disorders in their function revealed. Atoms with an unstable nucleus regain stability by shedding excess particles and energy in the form of radiation. An isotope of an element has 5 protons and 5 neutrons.
Bad Uses of Radioactive Isotopes. One example of a diagnostic application is using radioactive iodine-131 to test for thyroid activity Figure 154 Medical DiagnosticsThe thyroid gland in the neck is one of the few places in the body with a significant concentration of iodine. Radio-isotopes that have short half-lives are preferred for use in these drugs to minimize the ra-diation dose to the patient.
Which phrase best describe radioactive isotopes. What are the problems associated with the use of radioactive isotopes. This type of compound is called a radioactive tracer or radioactive.
