A further consideration ir the bets dose to the hande resulting fron
handling objects contaminated with fallout material.

although come data are

avallable on bete burns from handlin: radloactive objects, the conditions
are s0 different from those associated with faliout that comparisons proba-

bly would not be vwelid.*#
Tf the above assumptions and calculations are correct sencerning con~
tamination of a general area from fallout, then the transfer of 411 the
radioactive material to the hands from an object of equal area would not
constitute a hasard.

Thus, one might consider using as criteria for son

itoring objects, the doce readings given above for monitoring persannel

'

euvsice the general radiation field.

Eowewer, the problem is more complex since the hands say cone into

eontact with contaminated surfaces many tices larger in ares than the
hands, with an unceternined percentage of activity being transferred to
the hends.

Of course, an added uncertainty is the frequency of washing of

the hand» and/or the rubbing off of the material frox the hands,
Furticr, one might speculste that a given surface could have signifie
cantly higher contarination than the general ares and NG handiing of
auch @ surface could constitute a greater risk,

This might be true because

of the greater amount of activity transferred to the hands or because of
the doses delivered during the time of actually handling the object.

The

uncertainty of the percentage of transfer of saterial has been mentioned,
(ne uncertainty in the second case is the length of tina the object would
be handled.
