Art. 45 Dose constraints and dose calculation

1 In re­search pro­jects with no ex­pec­ted dir­ect be­ne­fit, a dose con­straint of 5 mSv per year (ef­fect­ive dose) ap­plies to the par­ti­cipants.

2 In ex­cep­tion­al cases, the dose con­straint spe­cified in para­graph 1 may be up to 20 mSv per year (ef­fect­ive dose), with con­sid­er­a­tion be­ing giv­en to age, fer­til­ity, life ex­pect­ancy and health status, provided that this is ab­so­lutely es­sen­tial for meth­od­o­lo­gic­al reas­ons.

3 In the case of com­bined pro­ced­ures, all ra­di­ation sources must be taken in­to ac­count in the cal­cu­la­tion or es­tim­a­tion of the dose to par­ti­cipants.

4 In the cal­cu­la­tion or es­tim­a­tion of the dose, the un­cer­tainty factor must be taken in­to ac­count.
