decontamination of painting on metal surface by dry ice jet was carried out.The influence of jet parameters on decontamination efficiency was examined.The results showed that the painting weight loss decreased with increasing speed of jet movement.The optimized parameters were target distance of 25 mm
jet angle of 63°
and the pressure of 0.6 –0.7 MPa
with a filtration efficiency of over 99% and 5.8–9.0 μm particle sizes of the aerosol.For the painted samples polluted by 137Cs and 235U
the decontamination effect is excellent.For the polluted plumbum kettles
this method is effective.Therefore
the dry ice jet is an excellent technology for painting on metal surface.
