Radiation dose increases in proportion to time.

Stay as far awayas possibleុᩉỉᾁʈỆӒൔ̊• The radiation dose decreases in inverse proportion tothe square of the distance from the radiation source.

– Make the working time as short as possible!
– Do a “Cold run” practice and understand the individual steps of eachprocedure.

– Keep as much distance between yourself and the radiation
source as possible!
– Don’t touch the radiation source directly.
– Use remote handling equipment such as tongs or forceps.
