Explore: Radioactive Tracers In Pesticide Research

it conducted research on TCA, which it sold under the tradename Tecane Insecticides had radioactive tracers to test uptake by insects. In 1942, the herbicide

into it; pesticides programs were transferred from the Department of the Interior, Food and Drug Administration, and Agricultural Research Service; and

intimately involved with the use of radioactive tracers in medicine. Over 10,000 hospitals worldwide use radioisotopes in medicine, and about 90% of the procedures

radioactive tracers in biochemical laboratories. These are: 32P, a beta-emitter (1.71 MeV) with a half-life of 14.3 days, which is used routinely in life-science

found in the Earth's crust is a mixture of seven primordial nuclides, barium-130, 132, and 134 through 138. Barium-130 undergoes very slow radioactive decay

from them. The biodiffusion coefficient is usually measured using radioactive tracers such as Pb210, radioisotopes from nuclear fallout, introduced particles

chloride with neutrons. The isotope 35S is used in various sulfur-containing compounds as a radioactive tracer for many biological studies, for example, the

decay of radioactive materials present beneath the Earth's crust, and nuclear fission relies on man-made fission of heavy radioactive elements in the Earth's

the highly radioactive 65 Zn, which has a half-life of 244 days and produces intense gamma radiation. Because of this, zinc oxide used in nuclear reactors
