If documents are to be saved from destruction by mould, prevention of further fungal growth is a must-have!
A very effective mould growth inhibition method used by Rhenus is X-ray irradiation, whereby the microorganisms present in contaminated documents are destroyed by means of electronically-generated X-rays. The minimum irradiation dose required to inhibit mould proliferation is determined on a case-by-case basis based on scientific reasearch and operational experience.
Since X-rays do not cause radioactive contamination, the documents will be absolutely residue-free after the X-ray treatment.
Successful treatment will be ascertained by means of a microbiological investigation evidencing the documents‘ restored safety.
