A dosimeter system for determining radiation exposure including first and second units, where the first unit determines a first quantity indicating influence of a first radiation field, and transmitting the first quantity by the first detecting-unit to the second unit, where the second unit determines second quantity indicative of influence of a second radiation field on biological tissue, third detecting-unit determines a third quantity indicative of an influence of the second radiation field, where the third detecting-unit is of the same type as the first detecting-unit included by the first unit, and determining quantity for adjusting the first quantity on basis of the second quantity by the second detecting-unit and third quantity by the third detecting-unit, adjusting the first quantity so a fourth quantity indicative of an influence of the first radiation field on biological tissue based on the first quantity by the first detecting-unit and adjusting the first quantity.
