CERN did in 1999 and 2000 some extensive radiation tests of the 16 channel INFN front-end electronics board including 4 MAD chips, preamplifiers, and I2C chips. In short: Tests were performed with gammas, slow and fast neutrons, and with different types of ions. Conclusion: no dynamic or static changes found so far. (For terms and abbreviations like SEL, SEU etc see http://en.wikipedia.org/wiki/Radiation_hardening) (The W&M MAD chips are sometimes called MAD4 or NEWMAD in the reports below) Link to the radiation damage reports: http://wwweda.pd.infn.it/cms/DTFB/electronics/frontend/documenti/radiation.pdf http://wwweda.pd.infn.it/cms/DTFB/electronics/frontend/documenti/rad2000.pdf Taken from the MAD chip homepage: http://www.pd.infn.it/cms/DTFB/electronics/frontend/homepage.html I attached both reports in case the above links don't work anymore. .
