Dear all,

It is probably wise to recirculate some material and instructions.

Please, find enclosed as attachment files the instructions for isotope work in our facilities.

When you start doing isotope work for the first time in our isotope laboratory, contact me.

Dosimeters: I am able to tell whether you need it or not. Groups are going to order and pay them.

Health inspection: Law says that when a person starts doing "säteilytyö" i.e. work where you can get radiation in amounts that doses have to be followed you have to go to health inspection before (if you belong to class A) you start working, or at latest after one month when you have started working (class B).

No one in our laboratory - at this moment - belongs to class A.

All those who will or who should use dosimeters should definitely go to health inspection - if you do not you will break law, without any doubt or question of interpretation.

Others: if you are student - not employee -, and/or you will use radiation only very few times, some kind of common sense may be used - but basicly all who work with isotopes should go to the medical check before they start their work.

Best wishes

Pekka

Säteilytyöllä tarkoitetaan säteilyn tai ydinenergian käyttöön liittyvää työtä tai tehtävää, jossa työntekijä voi altistua siinä määrin säteilylle, että työpaikalla on järjestettävä säteilyaltistuksen seuranta.
