Information for guest scientists on the hazards present at the ILL

The ILL is dedicated to helping its visiting researchers to make the most of its facilities. Neutron beams and instrument access are provided free of charge for proposers of accepted experiments.

The ILL User Club provides online access to all the information and administrative tools for our scientific visitors, presented in a user friendly environment.

1. Conventional hazards

The conventional hazards which may be encountered when preparing and conducting an experiment on an ILL instrument are divided into two categories:

  • the hazards inherent in any activity carried out in the ILL’s experimental work areas, namely fire, electrical and material handling hazards.
  • the specific hazards associated with the experiment or its preparation, which can be: fire/explosion (flammable substances), chemical hazards (dangerous gases, toxic substances), biological hazards, non-ionising radiation (ultraviolet (UV), infrared (IR), lasers, magnetic fields), cryogenics, work at height.

NB

  • If you need to make use of the chemistry laboratories, you must complete an online training module beforehand (you can access this module via the Visitors Club). In addition, on your arrival, you will be given an introductory safety tour by the Laboratory Responsible.
  • For information on biological hazards, please see the relevant section: Important instructions for biological samples

2. Radiological hazards

The experimental areas are either Radiation Supervised Areas or Radiation Controlled Areas. However, the level of exposure of guest scientists to ionising radiation corresponds to the radiation protection classification “non-exposed worker” for the use of all of the ILL instruments, with the exception of the instrument PF2 for which classification as a category B worker is required. (For information: Non-exposed: annual dose of less than 1mSv; category B: annual dose of less than 6 mSv).

NB

  • To obtain authorisation to access the experimental areas, you must complete the online health physics training module (you can access this module via the User Club).
  • The ILL assigns a passive dosimeter and an electronic dosimeter to all guest scientists in order to quantify the doses received in its installations. Guest scientists who already have a passive dosimeter from their employer must wear this dosimeter in addition to those provided by the ILL.

3. Safety requirements

Guest scientists must comply with the safety regulations set out in the documents they are given (user handbook, health physics regulations, special instructions for specific experiments, laboratory information leaflet).
