The internal dosimetry user group position statement on molecular radiotherapy.

Area of Science:

• Medical Physics
• Nuclear Medicine
• Radiotherapy

Background:

• The Internal Dosimetry User Group (IDUG) promotes dosimetry in molecular radiotherapy.
• The Ionising Radiation (Medical Exposure) Regulations 2017 (IR(ME)R) mandate dose optimisation and verification for molecular radiotherapy.
• Current UK molecular radiotherapy practices frequently do not meet IR(ME)R requirements.

Purpose of the Study:

• To address the gap in IR(ME)R compliance for molecular radiotherapy in the UK.
• To propose actionable steps for stakeholders to ensure regulatory adherence.
• To support the advancement of molecular radiotherapy through improved dosimetry practices.

Main Methods:

• The study identifies non-compliance with IR(ME)R in current UK molecular radiotherapy treatments.
• IDUG has developed ten specific points of action for legislative implementation.
• The group urges stakeholder support for these proposals.

Main Results:

• Many molecular radiotherapy treatments in the UK are not fully compliant with IR(ME)R.
• There is a risk of further deviation from compliance, potentially leading to suboptimal patient therapies.
• IDUG's ten proposed actions aim to facilitate successful implementation of the legislation.

Conclusions:

• Urgent action is needed to align UK molecular radiotherapy with IR(ME)R standards.
• National provision must be enhanced to meet compliance criteria.
• Implementing IDUG's proposals is crucial for patient well-being and the future of molecular radiotherapy.
