Mass Loading values for Children at Playgrounds

[James Weldy <jweldy@cnwra.swri.edu>]

I am performing a dose assessment which involves a scenario in which the

dirt on the ground at a playground is contaminated. I am looking for a

reference to support a value for the concentration of dust in the air that a

child playing at the playground is exposed. I have not been able to find

anything in my searches to this point. If anyone could point me to an

appropriate reference for this value, I would appreciate it greatly.



Thanks,
