9. Conclusion

Today, there are two main types of dosimetry. Passive dosimetry uses film or thermoluminescent materials, while active dosimetry uses electronics and computers.

Passive dosimetry is part of a well-established system, and the cost of a dosimeter renewed monthly or quarterly is modest. It provides cumulative dose information only a posteriori, but is well suited to situations where exposure risks are low, or in cases of accidental exposure at high dose rates, where it has the advantage of being less sensitive to detector saturation effects than active dosimetry. However, little progress seems to be expected in passive dosimetry today.

Active dosimetry remains a rapidly evolving field. It enables dose and dose rate to be monitored in real time. Currently, for high dose rates (several Gy/h), detectors can become saturated, necessitating additional...
