that was missing for nearly two days was left in a rural area about a kilometer (about a half-mile) from Hueypoxtla, a farm town of about 4,000 people.
The truck was transporting the cobalt-60
from a hospital in the northern city of Tijuana to a radioactive waste storage center, and was stolen in Tepojaco, central Mexico's Hidalgo State, Mexican authorities said in a report sent to the Vienna-based International Atomic Energy Agency (IAEA), which announced the theft earlier Wednesday.
Owing to the short cobalt-60
half-life, the doses significantly diminished with time.
Having some Cobalt-60
sources for the research irradiator in the agriculture center not secure and not used, posed some threat, actually a lot of threat on the public, on Lebanon," said Muzna Assi, Section Head of Radioactive Waste Management and Safe Transport of Radioactive Sources at LAEC.
The International Atomic Energy Agency said in a statement that a plane carrying 36 Cobalt-60
sources -- each one radioactive enough to kill a person within minutes -- arrived in Russia from Lebanon on August 30.
Personally, I have no fear of nuclear power stations, after all cobalt-60
, a radioactive isotope, is used in the treatment of cancer.
To determine the tolerance doses of cutaneous and mucosal tissues of normal birds in order to provide more effective radiation treatment for tumors that have been shown to be radiation responsive in other species, ingluvial mucosa and the skin over the ingluvies of 9 ring-necked parakeets (Psittacula krameri) were irradiated in 4-Gy fractions to a total dose of either 48, 60, or 72 Gy using an isocentric cobalt-60
Samples were irradiated at absorbed dosages of 0, 5, and 10 kGy in a cobalt-60
source irradiator at about 18 C.
is used all over the world for medical and engineering purposes.
Nuclear power plants use cobalt-59 as an adjustor or control rod, which is converted to radioactive cobalt-60
during the nuclear reaction process.
Cesium-137, strontium-90, cobalt-60
, and other potential bomb ingredients are reactive metals.
But the IAEA says there are more than 10,000 sources designed for radiotherapy each containing 1,000 pellets of strongly radioactive cobalt-60

That has happened in the case of some teletherapy sources, which usually contain cobalt-60
in kilocurie quantities and hence meet NRC criteria for high security concerns.
