Bioassay Program Design

DOE-STD-1121-98

listing of arrangements between the internal dosimetry program and the bioassay

measurements laboratory, including

-needed turnaround times

-MDAs for special and routine samples

-priorities for classification of samples (e.g., routine, special, emergency)

3.1.2 Bioassay Program Design

physical and chemical characteristics of radioactive materials encountered in the

workplace

establishment of the type and frequency of measurements to be used (RadCon

Standard 522.3)

derivation of decision levels

default trigger levels

preliminary actions to be taken for exposures to the different radionuclides present

at a facility following suspected or confirmed intakes at various levels

tailoring of investigations to a specific individual worker or exposure circumstances

documentation of the derivation of DILs

established DILs for each bioassay method applied for the analysis of all

radionuclides to which workers are likely to be exposed

if it is known or is likely that an individual has or could have intakes during the year

from different sources that could result in doses above the IL, methods to use to

derive an appropriately smaller DILs

methods of bioassay measurement and the rationale or justification for each

the MDAs for the bioassays

justification for the bioassay monitoring frequencies, including an evaluation of the

largest internal dose (i.e., minimum detectable dose) from an intake (acute or

chronic) that could go undetected with the chosen frequency

documentation and justification of a planned supplementary approach for intake or

dose assessment in case of technology shortfall

the rationale for the formal action procedures following a bioassay result

unexpectedly above the DL.
