NEW Rules for access to radiation protection areas

In accordance with the French decree 2018-437 regarding the protection of workers against the risks of ionising radiation, the ILL must implement new rules for users working in controlled areas. These rules will be applied from the first reactor cycle of 2023.
Users coming  for an experiment and working in the ILL’s experimental areas should now comply with the following rules:

Non-exposed (NE) Users

- For each authorised visit, upon arrival  Users must provide a signed authorisation form from their employer at the ILL ZAC entrance (Download here (pdf - 106 Ki), 106ki).
- The number of days worked in radiation protection controlled areas must not exceed 20 days in a rolling one-year period. This is Users' responsibility to monitor.
- Once non-exposed Users reach this limit they will not be able to participate in experiments scheduled within the rolling one-year period. Any Users expecting to go over the 20 day limit should therefore begin the formalities for becoming a classified (A or B) User in their home institution.

Classified Users (categories A and B)

- Only classified A or B users (exposed to ionising radiation) are allowed to work in the experimental areas for more than 20 days in a rolling one-year period.
However, it is classified Users' responsibility to come to the ILL with
 - Their employer's passive dosimeter
- Proof of medical fitness for Category A or B work (stating that you are apt to work with ionising radiation)

Further information for all Users

- The ILL continues to provide a non-nominative passive dosimeter to guarantee the measurement of neutron doses.il
- Nousers will be allowed to enter orange or red controlled areas under any circumstances.
- The Health Physics training test on the User Club website is mandatory for all Users (valid for 6 months).
