# An injectable dosimeter for small animal irradiations

## TL;DR

This paper introduces a new injectable in-vivo dosimeter using glass-encapsulated TLD rods for accurate dose measurement in small animal irradiations, allowing for dose validation in freely moving mice.

## Contribution

The novel injectable dosimeter enables in vivo dose validation in small animals, improving accuracy in complex irradiation scenarios.

## Key findings

- Reliable dose reconstruction within 10% of nominal dose
- Successful injection and use in 30 mice
- Applicable for inhomogeneous radiation fields

## Abstract

We have developed a novel in-vivo dosimeter based on glass encapsulated TLD rods. These encapsulated rods can be injected into mice and used for validating doses to an individual mouse in a protracted irradiation scenario where the mouse is free to move in an inhomogenous radiation field. Data from 30 irradiated mice shows a reliable dose reconstruction within 10% of the nominal delivered dose.
