RE: Mass Loading values for Children at Playgrounds

[Sonter Mark <sonterm@EPA.NSW.GOV.AU>]

Why don't you use IAEA Safety Series 115, which tabulates (Table II-VI)

sieverts per becquerel for ingestion for all radionuclides; you can also get

in the same reference the dose conversions for inhalation....

	Subject:	Mass Loading values for Children at Playgrounds



	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,
