When an irradiation accident occurs, it is very important for medical
treatment to be able to reconstruct the cartography of the dose absorb
ed by the irradiated person. The cotton textile 'dosimetric cotton' to
which an alpha-alumina dosimetric powder is fixed, has been devised i
n LPES-CRESA. It can be used to clothe persons subjected to irradiatio
n risks. By taking a number of precautions, the dose may be determined
from measurements of the thermoluminescence (TL). Some TL tests, whic
h are meant to describe the characteristics of the dosimetric textile
in various irradiation configurations, are described. In particular, i
t is shown that the dosimetric cotton is especially appropriate for ga
mma dosimetry in mixed neutron-gamma fields. It covers the field of ac
cident dosimetry extensively and the low detection limit actually obta
ined is 0.10 Gy.
