Investigation of radioactive radon daughters removal methods from copper surface
“New progress has been made in the suppression of radioactive background on copper surfaces in rare decay experiments. The researchers used a 5% citric acid and 8% hydrogen peroxide pickling formula to effectively remove 210Po from the copper surface, with a removal efficiency of up to 99.93%.”
