Safety Policy
- It is the policy of Rensselaer Polytechnic Institute to provide a safe and healthy environment for its students, faculty, staff and visitors I believe that the elimination of accidents that injure personnel and result in losses of property and equipment is everyone's responsibility.
Each person using the equip-ment and facilities of the Institute is expected to follow the procedures outlined in this manual, to supplement these procedures when necessary, to report all accidents promptly, and to bring to the attention of supervisors and faculty members any unsafe conditions or practices.
It is only through the dedicated efforts of everyone that accidents and injuries can be prevented and a safe healthy environment created for all to enjoy.
2.
Statement of ALARA
(
The radiation dose received by any person from external or t
internal exposure to ionizing radiation in a radiation in-l stallation (a controlled area in which radioactive material or machines generating ionizing radiation or both are used) must be held to the lowest possible value consistent with effective use of the installation and must never exceed the legally maximum permissible value.
Every effort should be made to avoid contamination of work areas, and, in any case, release of airborne or waterborne radioactivity must never exceed legal limits and every effort should be made to avoid accidental releases.
Disposal of all radioactive
- George Low, President i
- Rensselaer's Radiation Safety Regulations & Procedures
8 waste must be in accordance with procedures.
The radiation dose received by any person from external or internal exposure to ionizing radiation in a non-controlled area must be held as close to natural background levels as possible and must never exceed the legal maximum pennissible level.
Legal maximum permissible dose levels are those specified in the current edition of the New York State Department of Health Sanitary Code, Chapter I, Part 16, " Ionizing Radiation" and in Title 10, Part 20, of the Code of Federal Regulations (10 CFR 20).

19 3.0 Radiation Protection 3.1 Special Administrative Requirements (This function is inherent in the Radiation and Nuclear Safety Committee).
Rensselaer has not established an ALARA Committee.
Although the Policy Statement in Section 2.0 addresses ALARA, and is the basis for our program, the program at Rensselaer does not involve radiation exposures that would dictate a large effort. flowever, Rensselaer is committed to the ALARA concept and strives to maintain both radiation e)posure to people and the quantities of radioactive wastes to a minimum.
3.2 Technical Requirements 3.2.1 Access Control 1.
Controlled areas Areas at RPI are controlled radiation areas when:
(a) Storage or Use areas for special nuclear materials 2
(b) Loose contamination levels exceeding 1000 dpm/100 cm 2
beta-gamma or 100 dpm/100 cm alpha (c) Radiation levels exceed 2.5 mrem / hour (d) Airborne radioactive contanination exceeds 25%
of MPC 2.
Personnel Monitoring Personnel monitoring is the process by which an in-dividual is monitored to determine the radiation exposure he or she receives. This is accomplished by the wearing of devices sensitive to the radiations emanating within the installation where the individual has authorized access.
The overall process includes
20 periodic distribution and collection of the monitoring devices, processing of the devices to determine the radiation exposure or dose received by the wearers, interpretation and evaluation of the results and maintenance of records. Any individual receiving an exposure above 100 mR in any week will be notified and interviewed by the Director of Radiation and Nuclear Safety, who may require a formal report from the Supervisor of the Raciation Installation. The Director of Radiation and Nuclear Safety will also notify the appropriate government agencies of any reportable exposures.
(a) Personnel Monitoring Devices Devices used for personnel monitoring must be of the integrating type, responsive to the radiations of interest and of sufficient sensitivity to be able to record accurately exposure levels of 1/10 of the radiation protection guides.
(" Accurately" should be i 10% of calibration radiations.)
(b)
Personnel Monitoring Wearing Criteria (1) Each person who may receive a dose in excess of 25 mrem per week must wear a personnel monitoring device.
(2)
Each person who has occasion to enter a high radiation area (greater than 100 mrem per hour) must wear a person-nel h~aitoring device.
21 (3) Personnel monitoring devices are changed on frequency not to exceed a monthly basis.
(4) Personnel monitoring devices record-ing whole body exposure must be worn between the waist and neck and on the front of the trunk of the body.
(5) Other regions of the body (i.e., the extremities) may be monitored but only by devices explicitly provided for the purpose. Devices provided for whole body monitoring must not be used for this pe pose. These devices will be supplied upon request by the Office of Radiation and Nuclear Safety.
(6) These persornel monitoring devices must be worn at all times when the individual (aser, worban, or visitor) is within a Radiation Installation where monitoring devices are required.
(7) A protected repository in a secure non-radiation area must be used at each installation for storing the personnel monitoring device when not being worn. The Office of Radiation and Nuclear Safety will supply wall-mounted racks for this purpose upon request.
22 (c)
Personnel Monitoring Devices-Maintenance The Office of Radiation and Nuclear Safety shall be responsible for supplying person-nel monitoring devices to users, other employees of RPI and visitors to RPI Radiation Installations at the request of the Installation Supervisor.
(1) Requests for personnel monitoring devices are made by the Installation Supervisor to the Director of the Office of Radiation and Nuclear Safety.
(2) Personnel monitoring devices are ex-changed on a bi-weekly basis by the personnel of the Office of Radiation I
and Nuclear Safety.
(3)
Records complying with existing regu-lations are maintained by the Office of Radiation and Nuclear Safety.
(4)
Reports complying with existing regu-lations are prepared by the Office of Radiatico and Nuclear Safety.
(d) Personnel Monitoring - Visitors (1)
All visitors to Radiation Installations must conform to " Personnel Monitoring Wearing Criteria" above.
(2)
Visitor's devices may be obtained upon request of the Office of Radiation and Nuclear Safety.
24 3.2.4 Internal Exposure Contcol The special nuclear materials at Rensselaer are deemed non dispersable.
Therefore, internal radia-tion exposure is not a probable mode. However, if sus-Dected the use of a commercial vendor such as Teledyne Corporat on would be employed for dose assessment.
I 4%.
I* ts th);I )
23 (e) Records Access Individuals in the active personnel moni-toring listing can access their recoros and their records only from the RPI compu-ter. The signon and password are available 1
from the Director, Office of Radiation and Nuclear Safety. The only entry required is the individual's social security number.
Signoff is innediate following printout of records.
3.2.2 Ventillation Requirements The areas where the encapsulated special nuclear materials are used do not require ventillation. The special nuclear ma-terial encapsulation is of high integrity and the material is deemed non dispersable. However, fume hoods used at Rensselaer for dispersable radioactive materials maintain face velocities of 100 fpm and discharge through " absolute" filters if deemed necessary by the guidelines established in Rensselaer's Radiation Safety Regulations and Procedures. This document also dictates when stack monitoring is required.
3.2.3 Instrumentation The Office of Radiation and Nuclear Safety has available a full i
range of laboratory and portable radiation monitoring equipment.
The calibrating equipment ranges from proportional counting l
automatic sample changers to GeLi detectors.
The portable survey meters can detect and measure alpha, beta, gamma and neu-trons. The personnel monitors (TLD) are read in a Harshaw 2000 system.
