PROBLEM TO BE SOLVED: To provide a hot cell capable of improving cleanliness in a synthesis chamber.SOLUTION: A hot cell 10 includes a negative pressure chamber 22 capable of keeping an in-chamber pressure at a second pressure lower than an atmospheric pressure, and a positive pressure chamber (synthesis chamber) 21 capable of keeping an in-chamber pressure at a pressure higher than the negative pressure chamber 22. Thus, an outflow of radioactive material from the negative pressure chamber 22 to the outside of the hot cell 10 is prevented, and entry of foreign material such as dust or dirt from the negative pressure chamber 22 to the positive pressure chamber 21 is prevented. |
