How can radioactive isotopes be helpful and harmful?
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.

Radioactive isotopes have applications in agriculture, food processing, pest control, archaeology, and medicine.
What are the effects of radioisotopes?
When a person inhales or ingests a radioisotope, it is distributed to different organs and stays there for days, months, or years, delivering a steady radiation dose, until it decays or is excreted (committed dose). effects: hair loss, skin burns, nausea, gastrointestinal distress, or death (Acute Radiation Syndrome).

Why are radioactive isotopes biological spies?
Radioactive isotopes are called "biological spies" because they give scientists an insight into the activity of atoms in living organisms. Radioactive isotopes are easily detectable using technology, so their radioactive residue can be easily traced within organisms and analyzed.
Definition of Radioisotopes
Radioactive elements are elements that spontaneously emit radiation. The atomic number of this radioactive element is usually above 83, for example Uranium which has an atomic number of 92. Radioactive elements have an unstable ratio of neutrons and protons, so to stabilize themselves, these elements emit radiation.
Benefits of Radioisotopes
The following are some of the radioisotope names and their uses in a wide variety of fields, from health to industry.
Why are radioisotopes quantitative?
Results obtained from experiments in which radioisotopes are used are quantitative, because the amount of radioactivity present and available for detection is directly proportional to the radioisotope content of the sample being analyzed.
What are the instruments used to detect radioisotopes?
The most commonly used detectors are: (1) Geiger- Muller counters, which are employed primarily with isotopes emitting beta particles of intermediate or high energy (E max above 0.2 MeV) and which may also be used at low efficiency for the measurement of gamma radiation; (2) solid scintillation counters, which are generally employed with gamma ray- emitting isotopes ; and (3) liquid scintillation counters, which are used with isotopes emitting low- energy beta particles (E max below 0.2 MeV).
How is radiation energy measured?
Radiation energy is measured in electron volts (abbreviated eV), one electron volt being the kinetic energy acquired by an electron in an electrical potential difference of one volt. The beta particles and gamma rays emitted by radioisotopes that are often used as tracers have energies ranging from about 1 x 10 4 to 4 x 10 6 eV or 0.01 to 4.0 MeV (1 MeV equals 1 million electron volts).
What are the most common types of nuclear radiation?
The most common types of nuclear radiations are alpha particles, positive and negative beta particles, and gamma rays . Alpha particles, which consist of two protons and two neutrons and are therefore identical to helium nuclei, are emitted by radioisotopes of high atomic number (e.g., uranium, polonium, thorium, and radium) and are rarely used as tracers in biological studies.
Why is it so difficult to determine the distribution of a given element or compound in different parts of the body?
This difficulty may be compounded if certain components to be analyzed contain only trace amounts of the substance to be measured. Because radioisotope-containing compounds are not distinguished from their stable (nonradioactive) counterparts by an organism, the use of labeled compounds in studies of this sort can greatly simplify and reduce the number of analyses.
How are the rates of a substance incorporated by cells determined?
The rates at which different elements or compounds are incorporated by individual cells or by the body tissues, together with a determination of the specific loci of the deposition, can also be conveniently determined using radioisotopes.
What are the elements that have the same atomic number?
Isotopes are chemical elements that have the same atomic number (i.e., the number of protons in the nucleus of the atom) but different atomic masses (i.e., the sum of the number of protons and neutrons in the nucleus). Certain isotopes are unstable and undergo spontaneous nuclear changes (called transmutations) accompanied by the emission ...
How do radioactive isotopes dissipate energy?
A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical elementwith different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiationin the form of alpha, beta, and gammarays. Every chemical element has one or more radioactive isotopes. For example, hydrogen, the lightest element, has three isotopes, which have mass numbers 1, 2, and 3. Only hydrogen-3 (tritium), however, is a radioactive isotope; the other two are stable. More than 1,800 radioactive isotopes of the various elements are known. Some of these are found in nature; the rest are produced artificially as the direct products of nuclear reactions or indirectly as the radioactive descendants of these products. Each “parent” radioactive isotope eventually decays into one or at most a few stable isotope “daughters” specific to that parent.

What is the radioactive isotope used in smoke detectors?
Uses the radioactive isotope Americium-241 (half life 158 years) which sends steam of alpha particles to a sensor across an air gap. any smoke present will block the alpha particles and change the sensor signal, which creates the loud beeping noise you here when a smoke detector detects smoke.
Why do doctors use radioactive tracer?
radioactive isotopes give doctors the ability to "look" inside the body and observe soft tissues and organs. Radioisotopes carried in the blood also allow doctors to detect clogged arteries or check the functioning of the circulatory system. A radioactive tracer is chemically attached to a compound that will concentrate naturally in an organ or tissue so that a picture can be taken. This helps doctors to diagnose what is wrong with a patient and heal them faster.
What is iodine 131?
Iodine-131 is a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Japanese nuclear crisis.
Can radiation kill blood cells?
When humans are exposed to high levels of Radiation it can penetrate through our skin and kill blood cells and this heavy radiation can lead to cancer. Also people can be affected when they are receiving treatment for other cancers and the doctors may be using other radioactive elements eg.
Can radiation cause cancer?
Scientists have long known that radiation can cause cancer in humans. Radioactive energy waves are so small that they can pass through the body and harm a person's genetic make up found in their DNA. This is why you see strange mutations in animals and humans exposed to large amounts of radiation.

How does phosphorus help build bone?
Phosphorus works with calcium to help build healthy bone and teeth. These minerals are converted in the body into calcium phosphate salts that stiffen and strengthen bones. Phosphorus also regulates how much calcium is in the body and how much is excreted in urine.

people involved in major trauma, such as a severe burn (75 percent) people with sepsis (up to 80 percent) Low phosphorus can also affect people with certain diseases or medical conditions, including Cushing's disease, hypothyroidism, parathyroid disease, vitamin D deficiency, and malnutrition.
What is the role of phosphorus in the body?
These are minerals that the body needs to function normally. Although the main function of phosphorus is to build and maintain bones and teeth, it also plays a major role in the formation of DNA and RNA (the genetic building blocks of the body).
