1. Introduction

Future ICRP changes (2-3 y)
2006 new HAT model
2007 new ICRP recommendations
2007 wound model
2008 new OIR document (part 1)
2008 ICRP guidance document
2009- new OIR document (part 2)
It is highly likely that these will find their
way into EC legislation.

3. IMBA changes
What needs to be done?

Modify IMBA (and IMBA modules) to deal with the
latest dosimetry and models

• implement recycling directly

• implement HAT, RT models

• implement new SEEs (label based)

• implement all new systemic models

• radon

• quality assurance

3. IMBA changes
What needs to be done?

Evolution

• smooth transition

• compatible with previous calculations

• same look and feel

• extensive quality assurance
