Jill Reay

Director, Radiation Protection Adviser (RPA) & Monte Carlo N-Particle eXtended (MCNPX) Specialist

Jill was Aurora’s first employee and became a Director early in 2015. She is a well-respected RPA across the medical sector, contributing to the second edition of the reference book ‘Practical Radiation Protection in Healthcare’, and is a RPA2000 assessor.

Jill is one of Aurora’s specialists in Monte Carlo N-Particle eXtended (MCNPX) modelling, which is used for radiation shielding design, particularly for Proton Bean Therapy and other high energy external beam therapy facilities.


Jill’s interest in Radiation Protection started during her years as a BNFL sponsored student. After graduating from Imperial College London with a BSc (Hons) in Physics in 1992, she completed the MoD Graduate Trainee Health Physicist scheme at Devonport Royal Dockyard. Her HP role included training, accident response, preparing site licence documentation and undertaking ALARP reviews. She also set up a reassurance whole body monitoring service and, when she left, was responsible for the day to day management of the Dosimetry Office. In 1998 Jill changed her career direction and accepted a position as a Medical Physicist with the Regional Medical Physics Department based at Newcastle General Hospital. During her time in this post Jill specified, wrote and acted as system administrator for a new database to support the RMPD Approved Dosimetry Service, undertook acceptance and quality assurance testing of a range of diagnostic imaging equipment and acted as Radiation Protection Adviser and Medical Physics Expert to a number of hospitals and dental practices.
