Thorium 230 is an alpha emitter with half life 75,380 years. Therefore it is dangerous if ingested. Alpha particles don't penetrate the skin, so it would not be dangerous to handle carefully, but if ingested alpha particles can damage internal organs. Thorium 234 is a beta emitter with half life 24.1 days. So 230 is the more dangerous.
The difference between the lowest temperatures refers to the numerical value that represents the interval between the two lowest recorded temperatures. It is the result of subtracting the lower temperature from the other to determine their difference.
Thorium welding rods offer several advantages over other types of welding rods. They provide better arc stability, higher current-carrying capacity, and improved heat resistance. Additionally, thorium rods have a longer lifespan and produce less spatter during welding, resulting in a cleaner and more efficient welding process.
The difference between two temperatures is the numerical value that represents how much one temperature is larger or smaller than the other. To calculate the temperature difference, you subtract the lower temperature from the higher temperature.
An absolute threshold is the smallest amount of stimulation needed for a sensation to be detected, while a just noticeable difference is the smallest detectable difference between two stimuli. In other words, the absolute threshold is about detecting the presence of a stimulus, while the just noticeable difference is about discriminating between two stimuli.
The potential difference between two spherical shells is the difference in electric potential energy per unit charge between the two shells. It is a measure of the work required to move a unit positive charge from one shell to the other.
One is an idea and the other a big dangerous animal.
1. The external irradiation from thorium is not so important. 2. Inhalation or ingestion of thorium is dangerous because thorium is radioactive (it is an alpha emitter) and also release radon by decay.
Thorium can be separated from other elements by solvent extraction with tributylphosphate.
To obtain pure thorium metal it is necessary to separate thorium from other elements.
Thorium as a metal is obtained by a calciothermic process from thorium dioxide. Other methods are: electrolysis of thorium tetrafluoride and thermal decomposition of thorium tetraiodide (Van Arkel-de Boer process).
police dogs are trained to sniff out drugs and other dangerous stuff such as like bombs.
Important minerals of thorium are: monazite, thorite, thorianite, allanite.
Thorium can react with the majority of the other nonmetals.
Thorium B is 212Pb: radioactive isotope of lead. Thorium D is 208Pb: stable isotope of lead.
Thorium can be strip mined and it could be deep mined. It is be produced as a byproduct of the production of rare earth elements, and since the current production as a byproduct far exceeds the demand, it is not usually mined.
Thorium primarily forms compounds with elements such as oxygen, fluorine, sulfur, and carbon. It can also combine with other elements such as nitrogen, phosphorus, and various metals to form a wide range of thorium compounds.
