There are two major reasons. The first is that anesthetic gases have a very similar effect on humans as they do on animals - you don't want to sedate or anesthetize the humans performing surgery. The second is that anesthetic gases, in large doses or over a long period of time, can have significant health effects. Over many years, persons exposed to large amounts of anesthetic gases have increased risks of pulmonary disease and cancer.
an anesthetic is a drug that numbs your sensation and sometimes dampens your alertness. There are many types of anesthetic including topical (benzocaine cream for example), local (a novacaine injection at the dentist for example) and general (which is what they would use to "knock you out" for a major surgery)
the definition of anesthetic would be anesthetic- (n)a substance that causes loss of sensation or consciousnesshope
A contact exposure would typically be in your system immediately after contact occurs. The duration it remains in your system can vary depending on the type of contact and the substance involved. It's important to wash the affected area thoroughly after contact to minimize any potential absorption into the body.
Sometimes. When we have to do something and the patient would feel pain, we often give them an anesthetic so they don't feel it.

There are many uses. Generally the main use is using as a anesthetic.
I think the anesthetic is included in the cost of the surgery.
A pleasure craft would produce the highest concentration of carbon monoxide in areas where the engine is running at high RPMs, particularly in enclosed or poorly ventilated spaces such as engine compartments or marinas. Additionally, idling in confined areas can lead to a buildup of exhaust gases, increasing carbon monoxide levels. It's crucial to ensure proper ventilation and avoid prolonged engine operation in these conditions to minimize exposure.
Depends on what anesthetic you use. For an anesthetic which is really just an extreme pain reliever, they use a nitrous/oxygen which is sometimes called 'Laughing gas'. It is so called because in small doses it would give the patient a sensation of uncontrollable giggling fits. To put someone to sleep they use the same gas but on a larger scale. The patient breathes it in voluntarily the they use a 'feeding tube' to deliver the gases straight to the lungs where they get immediately distributed to the blood streams. Sometimes though they would use the liquid version of a general anesthetic first; evoflurane,Isofluruorane and halothane. Then they would use the other anesthetics afterwards.
Uranium Tetrafluoride (UF4) itself does not emit millisieverts directly; rather, it is a form of uranium that can release radiation due to the decay of uranium isotopes. The radiation exposure in millisieverts from UF4 would depend on factors such as the concentration of uranium, the specific isotope present, and the duration of exposure. Generally, UF4 is handled in controlled environments to minimize radiation exposure, and any potential dose would be assessed based on specific circumstances.
