Significance and Use | ||||||||
4.1 Absorbed dose in a material is an important parameter that can be correlated with radiation effects produced in electronic components and devices that are exposed to ionizing radiation. Reasonable estimates of this parameter can be calculated if knowledge of the source radiation field (that is, energy spectrum and particle fluence) is available. Sufficiently detailed information about the radiation field is generally not available. However, measurements of absorbed dose with passive dosimeters in a radiation test facility can provide information from which the absorbed dose in a material of interest can be inferred. Under certain prescribed conditions, TLDs are quite suitable for performing such measurements. 1.1 This practice covers procedures
for the use of thermoluminescence dosimeters (TLDs) to determine
the absorbed dose in a material irradiated by ionizing radiation.
Although some elements of the procedures have broader application,
the specific area of concern is radiation-hardness testing of
electronic devices. This practice is applicable to the measurement
of absorbed dose in materials irradiated by gamma rays, X rays, and
electrons of energies from 12 to 60 MeV. Specific energy limits are
covered in appropriate sections describing specific applications of
the procedures. The range of absorbed dose covered is approximately
from 10−2 to 104 Gy (1 to 106
rad), and the range of absorbed dose rates is approximately from
10−2 to 1010 Gy/s (1 to 1012
rad/s). Absorbed dose and absorbed dose-rate measurements in
materials subjected to neutron irradiation are not covered in this
practice. (See Practice E2450 for guidance in mixed fields.)
Further, the portion of these procedures that deal with electron
irradiation are primarily intended for use in parts testing.
Testing of devices as a part of more massive components such as
electronics boards or boxes may require techniques outside the
scope of this practice.
1.2 This standard dose not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
