Can anyone be around the HPLC instrument often? Will there be radiation?

Generally, electronic instruments have electromagnetic radiation more or less. The shell of mechanical and electrical equipment imported regularly is marked with electromagnetic protection level and precautions. Operate in strict accordance with the instructions, and the equipment should be grounded reliably. Do not use tools to open the shell, especially medical equipment with radioactive sources. Fortunately, the chromatograph is only ordinary electromagnetic radiation, and the anti-static cotton overalls can resist it.
