ness and cataracts can result from a high dose received over a
short period. Stochastic effects such as cancer or genetic muta-
tions are cumulative, resulting from multiple exposures over the
long term. Just because surgical personnel won't see stochastic
effects right away doesn't mean they're not at risk.
"Lead aprons and standing at a distance are the only ways for
staff to mitigate exposure," says Mr. Launders. Aprons (or vests
and skirts) and thyroid shields incorporating a 0.5mm lead-equiva-
lent material are a must for users and bystanders alike. Leaded
goggles (or glasses with side shields) and gloves add protection
for those at the table. While mobile C-arms render fixed shields
impractical, leaded glass screens on rollers and lead-lined table
drapes that block scatter from beneath may work.
If there's nothing to stand behind, though, just stand back.
