A laboratory air sampler, that has high mobility and reduced operational noise, has been developed. It is used to collect the air-borne particles in such areas that are out of daily watching by stationary monitors or contaminatated accidentally by radioactivity.
Primary considerations in the design of the instrument are (1) to reduce external size and weight, (2) to deduce operational noise. Noise level is less than 53-59 phones at a distance of one meter away from the instrument.
Various filter paper and active carbon cartridge filter for the filteration of iodine can be installed in a filter box at the top of the instrument and easily replaced.
