The Environment Health and Safety Department (formerly TSO) is the organizational unit that provides administrative and technical services in support of the ISU Radiation Safety/Protection Program.

ISU ALARA Policy and Exposure Controls
The University is committed to an effective radiation protection program to eliminate unnecessary exposures to radiation and to reduce all exposures to levels that are As Low As Reasonably Achievable (ALARA), taking into account all social and economic considerations. The ALARA goals for Idaho State University are set by the Radiation Safety Committee (RSC) and are based upon the legal limits set by the Nuclear Regulatory Commission, good radiation protection practices, and when available, historical dose information for each active radiation program. The visitor ALARA goal is 100 mrem/calendar year (10 mSv/yr) or 25 mrem/calendar quarter (2.5 mSv/qtr).
The Environment Health and Safety Department (formerly TSO) monitors all exposure records and will report your exposure if greater than the minimum detectable amount (10 mrem or 0.1 mSv) to you or your employer at least once a year. At any time in the future, you may request from the EHS your exposure received at ISU.
The embryo-fetus is more susceptible to radiation effects than an adult. The dose limit for the embryo-fetus is 500 mrem (5 mSv) during the entire gestation period. As a further precaution, it is advisable to keep the monthly doses below 50 mrem (5 mSv). This degree of protection for the embryo-fetus can only be achieved with the cooperation of the employee, who should notify her sponsor or the RSO as soon as the pregnancy is known by completing a Pregnancy Declaration.
- Each individual is responsible for their own exposure and should make every reasonable attempt to maintain their exposure ALARA by uses of time, distance and shielding and by following the guidance of your sponsor. Your sponsor is also responsible for your personal conduct and access to radiation and radioactive materials.
- Each visitor’s dosimetry badge is to be used only by one individual, then returned to the EHS when it is no longer needed. The badge will only be issued for one quarter. If the individual will need the badge beyond this period, that person must attend an initial Radiation Safety Training Session and will then be issued a permanent dosimeter.
- The dosimetry badge can be issued for a group tour, with one person in charge to wear the badge. Each member of the group must supply all of the information that is normally required when the dosimeter is issued for individual use.
Any question concerning radiation safety should be directed to the EHS in Room 101 in the Physical Science Building or at phone 282-2311.
