Radiation Guide 1.7 - Guide for the Preparation of Applications for Analysis of Leak Test Samples
- Radiation Guide 1.7 - Guide for the Preparation of Applications for Analysis of Leak Test Samples is also available in Portable Document Format (PDF, 75KB, 25pg.)
APPLICATIONS WHICH DO NOT FOLLOW THE FORMAT AND CONTENT OF THIS GUIDE CANNOT BE REVIEWED AND WILL BE RETURNED FOR REVISION.
1.1 Purpose of Guide
This guide describes the type of information that should be submitted in applications for specific licenses for the possession and use of radioactive material for the purpose of analyzing samples for radioactivity. It includes the general principles that will be considered in evaluating an applicant's proposed radiation safety measures.
The New York State Department of Health will normally issue a single license to cover the laboratory's entire radioisotope program. Separate licenses are not normally issued to different departments of a laboratory, nor are they issued to individuals associated with the laboratory.
The applicant should carefully study the regulations and this guide, and should submit all information requested. The Department will request additional information when necessary to provide reasonable assurance that the applicant has established an adequate radiation safety program. Such requests will delay final action on the application.
Three general principles that will be considered in evaluating proposed radiation safety measures are recognition by the laboratory of:
- The management's1 responsibility for the safety of employees and the public;
- Its responsibility for maintaining off-site releases as low as is reasonably achievable (ALARA) and avoiding significant increases in environmental radioactivity; and
- Its responsibility for minimizing exposures to employees.
1Management is defined as those persons authorized by the charter of the institution to make its policies and direct its activities.
1.2 Purpose of Appendices to Guide
The regulations require that the licensee develop and implement procedures that will ensure compliance with the regulations. Appendices to this guide describe model radiation safety procedures. Each applicant should carefully read the applicable regulations and model procedures and adopt them as written whenever possible. If you are unable to adopt a particular procedure as written, submit a copy of the procedure in the guide with your changes indicated in red ink. You must keep copies of these procedures with the license document when it is issued since they will be made a part of the license at that time.
1.3 Applicable Regulations
All regulations pertaining to this type of license are found in 12 NYCRR 38 of the New York Code of Rules and Regulations.
1.4 As Low as is Reasonably Achievable (ALARA)
Part 38 requires that persons who operate or permit the operation of radiation installations shall make every effort to maintain radiation exposures and releases of radioactive material as far below the limits of Part 38 as is reasonably achievable. License applicants should give consideration to the ALARA philosophy in the development of plans for work with radioactive materials.
2. Filing an Application
You, as the applicant for a materials license, must complete DOSH Form 236 (7/06). You should complete Items 1 through 4 and 18 on the form itself. For Items 5 through 17, submit the information on supplementary pages. Each separate sheet or document submitted with the application should be identified and keyed to the item number on the application to which it refers. All typed pages, sketches, and, if possible, drawings should be on 8 ½ x 11 inch paper to facilitate handling and review. If larger drawings are necessary, they should be folded to 8 ½ x 11inches. You should complete all items in the application in sufficient detail for the Department to determine that your equipment, facilities, training and experience, and radiation safety program are adequate to protect health and to minimize danger to life and property.
You must submit two copies of your application with attachments. Retain one copy for yourself, because the license will require that you possess and use licensed material in accordance with the statements and representations in your application and in any supplements to it.
Mail your completed application and the required fee to:Center for Environmental Health
Bureau of Occupational Health and Injury Prevention
Empire State Plaza-Corning Tower, Room 1325
Albany, New York 12237
Applications received without fees will not be processed and the fee is non-refundable.

4. Amendments to Licenses
After you are issued a license, you must conduct your program in accordance with (1) the statements, representations, and procedures contained in your application; (2) the terms and conditions of the license; and (3) the Department's regulations.
It is your obligation to keep your license current. You should anticipate the need for a license amendment insofar as possible. If any of the information provided in your application is to be modified or changed, submit an application for a license amendment. In the meantime, you must comply with the terms and conditions of your license until it is actually amended; Department regulations do not allow you to implement changes on the basis of a submission requesting an amendment to your license.
An application for a license amendment may be prepared either on the application form or in letter form and should be submitted in duplicate to the address specified in Section 2 of this guide. Your application should identify your license by number and should clearly describe the exact nature of the changes, additions or deletions. References to previously submitted information and documents should be clear and specific and should identify the pertinent information by date, page and paragraph. For example, if you wish to change the RSO, your application for a license amendment should specify the new individual's name, training and experience. The qualifications of the new RSO should be equivalent to those specified in Item 6 of this guide.
