MITIGATING THE IMPACT OF CLIMATE CHANGE
Oral
Degradation of organic and especially cellulose based heritage is caused by both endogenous and exogenous factors. One of the most common exogenous factor is moisture, and the variation of the equilibrium moisture content of the material can initiate the development of mold in the substrate. Mold not only affects cellulose materials, but is also impacts occupational health and thus should...

MITIGATING THE IMPACT OF CLIMATE CHANGE
Oral
Cultural heritage artefacts of organic origins are susceptible to
deterioration by the action of insects, moulds, fungi and bacteria.
The infestation of museum store rooms, collections and sacral places
is a serious permanent worldwide problem to the safekeeping of such
objects.
Protecting cultural heritage objects against biodeterioration becomes
especially urgent when provoked by...

MITIGATING THE IMPACT OF CLIMATE CHANGE
Oral
Radiation sterilization was taken into consideration as mass decontamination techniques for the bio-degradable cultural heritage (CH) as soon it was spread in the medical field. Earlier experiments showed the advantages and disadvantages, namely “side-effects” on the CH materials. More than 50 years later, the suitability of ionizing radiation treatment for CH items is still under debate. The...

MITIGATING THE IMPACT OF CLIMATE CHANGE
Oral
The styrene unsaturated polyester resin is implemented so far by ARC-Nucléart Conservation Centre for the consolidation of degraded wooden artefacts from cultural heritage, following a process so called “Nucléart” by liquid state resin impregnation under vacuum/pressure, and in-situ polymerization of the resin under gamma irradiation. However, this method is irreversible due to the crosslinked...

MITIGATING THE IMPACT OF CLIMATE CHANGE
Oral
Ionizing radiation has specific and indisputable advantages over classical procedures for conservation and preservation in Cultural Heritage, such as no risk for the operators, no toxic residues and hence no risks for curators, visitors or the environment. This technology can replace the traditionally used toxic or carcinogenic gases such methyl bromide or ethylene oxide, eliminating the...

MITIGATING THE IMPACT OF CLIMATE CHANGE
Oral
Biocide treatment by $\gamma$-irradiation for wooden and archival
items has been proposed more than $50$ years ago, but, despite some
resounding success and a demonstrated real efficiency, it is still of
limited uses for heritage conservation. Indeed, if such denoted
“nuclear” process can scare the less scientific public, more
rational reluctance due to fear of negative effects induced...
