Tumour promotion under a power frequency magnetic field
The reported finding
Discovery dossier reports more and larger mammary tumours in a chemically initiated rat model.
Reading it carefully
Retrieve original and follow-up experiments; repeated Hannover papers are not separate laboratories.
Inside the study
Exposure conditions
50 Hz; 100 microtesla; 91 days reported in discovery dossier.
Design & controls
DMBA-treated rats; 99 exposed and 99 sham reported.
The protection question raised
Is the reported mammary-tumour promotion reproducible in this chemically initiated model? Original and follow-up papers remain retrieval work, and related Hannover publications are not independent laboratory confirmations.
