The success of a space mission is vitally correlated with the radiation hardness of the used electronic parts. Thus, the selection of the built-in parts will decide whether the electronics can withstand the radiation environment of a specific space mission or not. To assure for a proper part selection radiation hardness assurance measures need to be undertaken that are executed according specific standards [1]. According to this standard, Radiation Hardness Assurance (RHA) consists of all activities undertaken to ensure that the electronics of a space system perform to their design specifications after exposure to the space environment. A decent RHA that is performed on all the used electronic parts is costly in terms of time and money and is a burden especially for low-cost space missions that are using Components-Off-The-Shelf (COTS) parts [2].

In this light the use of existing knowledge, i.e. test and flight heritage, is of advantage to efficiently reduce development time and costs. However, the existing knowledge needs to be made available and conditioned for use – which could be realized by the usage of radiation effects databases.

Within the scope of this lecture, we present available radiation effects databases [3] - [6]. The structure of the databases are described and their differences are discussed. Useful characteristics of a database are reflected. Pro and Cons of database usage are discussed.
