Abstract (englisch):
Reliability of technical systems that measure safety or legally relevant values is of great importance. Such a device
is an automatically switching radon exposimeter, which is focused on in this contribution for reliability assessment.
In certain areas it is legally required to measure the radon dose on persons, which can lead to health risks like lung
cancer. An early evaluation of reliability helps to prevent costly iterations in production phase. The problem is, that
reliability data is hard to get in early stages of development, when most of the components are not even fixed yet.
Therefore, in this contribution the reliability is assessed by using available generic failure rates data for device
classes similar to the ones used in the radon exposimeter. Together with methods like reliability-block-diagrams
(RBD) and failure-mode-and-effects-analysis (FMEA) the failure rates and mean-time-to-failures (MTTF) are
calculated. Critical components are identified and improvements like redundancy are introduced to improve the
MTTFs. This helps product developers to avoid flaws and reduce risk of loss of function at an early stage, avoiding
