Dilution Perhaps the most common application of dilution is when an individual has been exposed to tritium, either thru inhalation, ingestion, or absorption. Drinking a lot of water will act as a diuretic and the tritium, which has combined with oxygen to form tritiated water, will be flushed out of the individual’s body.

Substitution The most recognizable application of substitution is the administration of potassium iodide to individuals who may be exposed to radioactive iodine. If the potassium iodide is administered before the potential intake then the thyroid will take up that iodine and not the radioactive iodine. If the potassium iodine is administered after the radioactive iodine intake then the non-radioactive iodine displaces the radioactive iodine to some extent.

If the potassium iodine is administered after the radioactive iodine intake then the non-radioactive iodine displaces the radioactive iodine to some extent. Chelation Chelation has proven successful for both radioactive and non-radioactive metals. Chelating agents similar to EDTA (ethylene diamine tetra-acetic acid) are used to make the radioactive metals in the exposed individual’s body more soluble so they can be eliminated more efficiently by the body’s mechanisms. For transuranic intakes chelation is most effective if administered within one hour of the intake. In those cases chelation has proven to remove as much as 90% of the radioactive material originally taken into the individual’s body.

Lung Lavage Lung lavage is a somewhat extreme medical procedure and the patient must be in good physical condition. However lung lavage has proven to be effective in removing small particles from the lungs of individuals incases such as coal miners or heavy tobacco smokers. In the medical procedure one lung is collapsed then filled with water (in the case of radioactive metals the water may contain a chelating agent) then the patient is gently rocked to get the water more deeply into the lung. The water is removed and the lung is re-inflated with air. Then the same process is performed on the second lung.

Those smaller particles can transfer to the blood stream at that point and can then travel throughout the body. Two measurement techniques provide a quick estimate of the amount of inhaled radioactivity. One is known as a nose swipe, which is simply using something like a Q-tip to swipe around the inside of the nose, then counting the radioactivity on the Q-tip. A second measurement technique is to perform a “chest count” which is using a high efficiency gamma detector to identify the radio-nuclide and measure its activity.

Injected Radioactivity Injected radioactivity is that caused by a radioactively contaminated item or a piece of radioactive material penetrating into tissue. Some of the radioactive material may remain in the wound after the object is removed. Injected Radioactivity Injected radioactivity is that caused by a radioactively contaminated item or a piece of radioactive material penetrating into tissue. Some of the radioactive material may remain in the wound after the object is removed. A quick estimate of the amount of radioactivity remaining in the wound can be made by using a hand-held radiation detector, one that is capable of measuring the type of radiation (alpha, beta, or gamma).

Physical and Chemical Form Physical and Chemical Form Physical Form The physical form of radioactive material may be as a gas, liquid, or solid. Gas is the most mobile while a solid is the least mobile. Both liquid and solid physical forms may exist in different particle sizes. Aerosols generally refer to physical forms that are very mobile due to being a gas or very small liquid or solid particles. Particles sizes smaller than 10 microns ( 2.54E-7 inches) in diameter can easily become airborne. However, particles with a high specific gravity will be less mobile. Particle sizes smaller than 5 microns are of greater concern than larger particles due to their greater mobility.

Chemical Form The chemical form of radioactive material determines how easily that radioactive material is taken into the body and how widespread it will become in the body. The less soluble chemical forms are generally less of a hazard once they are in the body than the more soluble chemical forms. However, the less soluble chemical forms tend to remain in the body for a longer period of time than the more soluble chemical forms. The chemical form of the radioactive material can change once it is in the body due to simple chemical reactions. Further, specific chemical forms tend to become attracted to different tissues in the body, such as the radioactive material collecting on bone or collecting in the blood or other tissues. Radioactive material in the body is routinely excreted from the body through feces, urine, and other bodily excretions. This excretion can be speeded up by various methods such as dilution, substitution, and chelation.

Physical, Biological, and Effective Half-life Physical, Biological, and Effective Half-life Physical half-life is the radioactive half-life of the material. Biological half-life refers to how long the radioactive material will remain in the body under normal circumstances. Effective half-life is combination of physical and biological half-life. Consider a long-lived radio-nuclide such as plutonium-239 with a physical half-life of 24,000 years. The biological halflife of plutonium-239 is from a few years to near 24,000 years depending on the chemical form of the plutonium-239. That biological half-life can be shortened by the use of a chelating agent that combines with the plutonium-239 and makes it more soluble which shortens the effective half-life to the extent that >90% of the plutonium-239 is gone in 1 year.

W hile it is less com m on than it once was, som e brands of gas lantern m antles incorporate thorium -232. In fact it is the heating of the thorium by the burning gas that is responsible for the em ission of light. Such m antles are sufficiently radioactive that they are often used as a check source for radiation detectors. Gas Lantern M antles.

In the past, prim arily 1920 through 1950, a wide range of radioactive products were sold as cure-alls, for exam ple, radium containing pills, pads, solutions, and devices designed to add radon to drinking water. The states generally have regulatory authority over these devices. In som e cases, a state m ight even require that these devices be registered or licensed. Most such devices are relatively harm less but occasionally one can be encountered that contains potentially hazardous levels of radium . If there is any question about the safety of such devices, the public is strongly encouraged to contact the state radiation-control program for advice. Antique Radioactive Curative Claims.

For the patient undergoing a PET scan the combination of the positron energy and the photon energy must be considered. 33 Positron Emitters Beta+ Energy and % Abundance C-11 N-13 O-15 F-18 Na-22 Al-26 V-48 Mn-52 Co-56 Ni-57 Co-58 Cu-62 Zn-65 Ga-68 As-74 Rb-82 Half-life 20.3 m 9.97 m 122 s 1.83 h 2.605 y 7.3E5 y 15.98 d 5.591 d 77.3 d 35.6 h 70.88 d 9.74 m 243.8 d 67.7 m 17.8 d 1.26 m MeV (%) 0.960 (99.8%) 1.199 (99.8%) 1.732 (99.9%) 0.634 (96.7%) 0.546 (89.8%) 3.210 (100%) 0.697 (50.1%) 2.633 (94.9%) 1.458 (19.0%) 0.737 (7.0%), 0.865 (35.3%) 0.475 (14.9%) 2.926 (97.2%) 0.330 (1.4%) 0.822 (1.2%), 1.899 (89.1%) 0.945 (26.1%), 1.540 (3.0%) 2.601 (13.1%), 3.378 (81.8%) Several of the positron emitters are useful in PET studies. That usefulness is somewhat offset by the cost of producing the radionuclides and the added complexity of radiation protection. For all of the positron emitters the energy of the Beta+ must be considered. Refer to the table of Beta Dose Rates for estimates of beta+ radiation exposure. Also, consider the annihilation photons when the positron comes into contact with a beta-, annihilating their masses and producing two 511 KeV photons. These photons present an external radiation hazard. For the patient undergoing a PET scan the combination of the positron energy and the photon energy must be considered. 33 Ci / g = 3.578E5 / (T 1/2 in years x atom ic m ass) GBq / g = 1.324E7 / (T 1/2
