In order to have access to LNS there are simple procedures to be followed, basically consisting in some forms to be filled in.

This procedures concerns:

• Those who perform (even occasionally) and for any reason, activities with ionizing radiation risk;

• People taking part in experiments, research groups or guests who use the LNS facilities (Accelerators, experimental apparata, TestSite CT or Portopalo di Capo Passero, etc.) even if they don't performs activities with radiation risk.

The attached form 1 must be filled in and signed with handwritten signature by the employer and sent by post or PEC. If it is transmitted by ordinary e-mail, the signature must be electronically certified. The forms, filled in and signed, must be submitted to LNS via email to ufficio protocollo and, in case of radiation activities, to servizio di radioprotezione, at least 20 days before the user's programmed activity starts. It will not be granted access if the modules are not delivered in time before the activity or whether they are incomplete or incorrect.

Occasional visitors who performs activity during periods shorter than a week and do not use LNS structures or who come to LNS during guided tours, seminars, meetings, workshops, conferences, etc. do not need to produce any documentation, but rather they will simply provide a personal identification document to the gateman at the LNS entrance, indicating a reference person (LNS personnel or affiliate) to be contacted.

Guest workers who wish to access the LNS radiation controlled areas or to carry out activities with ionizing radiation riks (using X-ray machines or radioactive sources or materials) must be authorized by their employer, classified for the purpose of radiation protection, trained by radiation risks and insured for accidents during activities at LNS. In this respect, they have to submit the following documents, delivering them to the radiation protection service at least before the start of the activities.

The forms are specific for non-INFN workers and INFN workers:

• Annex RP1 for non-INFN workers (employees of Universities, research Institutes, external companies or other organizations). It has to be written on headed paper and signed by the employer and by the worker.
• Annex RP2 for INFN workers.

LNS will provide specific information relating to the risk to which workers will be exposed during their activities at the Laboratories, as well as personal dosimeters and any other necessary protective equipment. In radiation classified areas, access is normally allowed to exposed (classified) workers only, in compliance with medical fitness dated not before then 1 year and with radiation protection training. Not exposed Workers (not classified), may enter the controlled area only if authorized from time to time by the Radiation Expert or by the Radioprotection Service, who will grant access depending on the doses, activity of the workers and time spent inside areas. In such cases, access card and personal dosimeters may be assigned. However, these workers must be previously informed and trained on the radiation risks inherent to their activity.

For external companies staff that have a contract with LNS who need to access in classified radiation areas, without exposing themselves to the risk present in the areas concerned (not exposed workers), must submit the form Annex RP3.

The request for access can also be demanded for a period including several experiments (not after the end of the calendar year following the submission of the request). In any case, any change to the data reported must be immediately communicated.

Guests of the LNS Guesthouse please refer to the procedures for guests not affiliated to any INFN department and for the INFN-affiliated personnel.
