Please be advised that your license expires at the end of the day, in the month, and year stated in the license. Until your license is terminated, you must conduct your program involving byproduct materials in accordance with the conditions of your NRC license, representations made in your license application, and NRC regulations. In particular, note that you must:

1. Operate in accordance with NRC regulations 10 CFR Part 19. " Notices, Instructions and Reports to Workers; Inspections," 10 CFR Part 20, " Standards for Protection Against Radiation," and other applicable regulations.

2. Notify NRC, in writing, within 30 days when the mailing' address on the license changes (no fee is required if the location of byproduct material remains the same). 3. In accordance with 10 CFR 30.36(b) and/or license condition, notify NRC, promptly, in writing, and request termination of the license when you decide to terminate all activities involving materials authorized under the license. 4. Request and obtain a license amendment before you:

Dear Mr. Bondick: I

'

- - . This is to provide the necessary information for completion of the .j . license renewal on the ' Whitehead Institute irradiator license. The - irradiator'i~s under the control of Professor Richard Mulligan, who * has been ' the' principal supervisor of that irradiator since-its 1 installation. ' As such, Professor Mulligan is the logical choice to- !

serve as RSO on,that license, since he.is the most knowledgeable r

' person at' Whitehead on its ' operation and use. .As with_ the I radionuclide license at Whitehead, the actual day-to-day radiation ! safety activities.are carried out by the MIT RPO staff through a' ;I contract with Whitehead, but Professor Mulligan is.the Whitehead I individual RPO. personnel ~ interf ace - most s closely with on the. i irradiator. :

. . . i In addition to the years '.. Professor Mulligan has gained direct ; experience on the Whitehead irradiator, he has also been involved ;

for several years and been " specifically trained . at MIT on a- , comparable irradiator unit. In my opinion, Professor Mulligan is 't ' fully qualified to serve as RSO under this license.

Please contact the me at 617-253-9217 if further~information is required. Yours truly, .&houW i F.X. Mass 6, CHP, CMP i Director, MIT Radiation ! Protection Programs

. ' Harvey F. Lodish, Ph.D. Member, Whitehead institute for Biomedical Research and Professor of Biology, Massachusetts institute of Technology, _ Cambridge, MA

Dr. Lodish received his A.B. degree in chemistry and mathematics, summa cum laude, from Kenyon College in 1962, and his Ph.D. degree in with Norton Zinder from the in 1966. Following two years of postdoctoral research at the M.R.C. Laboratory of Molecular Biology with Sydney Brenner and Francis Crick, he Joined the faculty of the MIT Department of Biology. He was promoted to Professor in 1976, and in 1983 was appointed Member of the new Whitehead Institute. He is also a member of the MIT Biotechnology Process Engineering Center.

Initially,19s work focused on translational control of protein synthesis, and on regulation of gene expression during differentiation of the cellular slime mold. Beginning in 1973, his laboratory has increasingly concentrated on the biogenesis, structure, and function of secreted and plasma membrane glycoproteins. He defined the biosynthesis and maturation of the vesicular stomatitis virus glycoprotein, identified the intracellular- organelles that mediate recycling of the asialoglycoprotein and transferrin receptors, and clarified the role of pH changes in delivery of iron to cells and recycling of the transferrin receptor. More recently, his group has elucidated steps in folding and oligomerization of several proteins within the endoplasmic reticulum, shown that exit of newly-made proteins from this organelle requires that they be properly folded, and developed probes for measurement of the redox state within the endoplasmic reticulum. His group has cloned and sequenced mRNAs encoding the erythrocyte glucose transporter, the anion exchange (Band 3) protein, the human asialoglycoprotein receptors, intestinal sucrose-isomaltase, the murine erythropoietin receptor, the calcitonin and endothelin receptors, and two subunits of the TGF receptor. These have been used to define the structure and synthesis of the proteins, to identify and sequence related genes that encode proteins of related physiological function, and, most recently, to elucidate the modes of signal transduction of the TGFE and erythropoietin

receptors and their roles in tumorigenesis. Another major focus of his ! research is on the biosynthesis, folding, oligomerization, and degradation cf

proteins within the endoplasmic reticulum. , 1

. 2. Exposure Minimization Methods: .,

, Radiation exposures can be minimized by the use of one, or a , combination of, the following radiation protection principals-

f a) . Time: Minimize the time spent in room WI-232 while the unit is inL operation. Make use of the preset time interval counter. .: ;

" b) Distance: Maximize the distance from radiation sources (such'as the' l radiation streaming from the sample chamber drawer). . The dose rate .; . within the room itself does not fall off as a function of'th'e inverse .| square, since the scattered secondary radiation emitted from the unit : ' shielding does not present a true point source configuration. j

l

c) Shielding: Shielding the primary radiation from the '7Cs sources is , . accomplished by the manufacturer through the use of lead. To calculate j , the shielding effectiveness, use the following formula: , . D(,) = D(,) (e ~"*) B ! i

. .

' Where: D(,) = Shielded dose rate at desired point D(,) = Unshielded dose rate at desired point - u = Linear attenuation co-efficient for 662 kev gamma ray in lead = 1.29 cur 2 - = X . Shielding thickness , = B Buildup factor to account for the secondary. ! scattered radiation produced in the shield = 2.7 :

' ,

For example; calculate the dose rate on contact with the six inch lead walls surrounding the sources: |

= D(,) D(,)(e -"*)B !

D(,) = 1,800,000 mQi x 3.3 Rem-cm2 /hr-mci x (15cm) 2 = 26,400 Rem / hour at 15cm (6 inches) . ;

' D(,) = 26,000 Rem /hr x (e -(i.29 x ts)) x 2.7 -

D(,) = 0.0003 Rem /hr or 0.3 mrem /hr at the shield wall ) .!

' R3GULATIONS AND PROCEDURES FOR USE OF THE GAMMA-CELL 40 IRRADIATION UNIT - '

1. Operauing Procedures !

a) Only persons approved by Dr Harvey Lodish or Dr. Richard C. Mulligan and. registered and trained by the Radiation Protection Office (RPO) will be authorized to operate the ; unit.

' b) The Gamma-Cell 40 unit'shall be operated and~ maintained in '

accordance with the AECL instruction manual. A copy of_the . manual shall be kept in the room (WI-232) housing the Gamma- !

Cell 40 unit. . c) No corrosive, explosive, pyrophoric or highly flammable' material shall be irradiated in the unit,

d) The door to room WI-232 will be kept locked when the room is_ i unoccupied. Only persons authorized to operate the Gamma- 1

Cell 40 unit will have access to the key. ;

l e) A log shall be kept in WI-232 of all use of the Gamma-Cell 40 j unit. Information recorded will include length of ! irradiation and name of operator, plus any unusual circumstances or occurrences. ' f) To minimize personnel exposure, operators should spend a minimum amount of time in the area immediately in front of the lock on the irradiation chamber door (approximately 10 mrem / hour.at 5 cm).

2. Emergency Procedures

In case of an emergency, the use of the unit will be ! discontinued, the room evacuated, and the Radiation Protection Office notified by calling 13-2180. In particular,_ the

. Radiation Protection Office will be notified for any of the following occurrences:

a) Higher than normal radiation levels are detected or suspected. !

b) There is any reason to question the proper functioning of the ! AC operated area monitor. '

c) There is any indication of malfunction of the Gamma-Cell 40 unit involving radiation protection.

A-1

L ^ . g . . ~ w .- . .. , v In the event that the Radiation Protection Office is notified of an emergency, qualified. RPO personnel will visit the Gamma-Cell 40 installation to determine the nature of the emergency. If the emergency involves a malfunction of the Gamma-Cell 40 unit, AECL will.be notified of the situation and the RPO assessment. Operation of the unit will be discontinued until repair has been completed by AECL or its authorized representative and the unit ; has been determined to be ready for safe operation by RPO.

3. Radiation Monitoring Requirements |

Monitoring requirements for the Gamma-Cell installation will ; include the following three categories: Personnel, Gamma-Cell 40 room (WI-232), and Gamma-Cell 40 unit.

a) Personnel: All personnel authorized to operate the unit will be provided with film badges by RPO. These will be worn ' whenever the person is in room WI-232. When not being worn, . the film badges will be stored in a location where they will ! be exposed only to natural background radiation. Prior to 7 authorization, all persons will be interviewed by a staff ' member of RPO, and registered as radiation workers. b) Gamma-Cell 40 Room (WI-232) : The ambient radiation levels in the room will be monitored by an AC powered instrument, supplemented as necessary by a battery operated survey meter. The instruments will be tested monthly by a member of RPO, and evaluated at monthly intervals.

Film badge monitors will be installed by RPO, and evaluated I at monthly intervals.

Monthly inspection surveys will be made by a member of RPO.

c) Gamma-Cell 40 Unit: Wipe tests will be performed by a member . of RPO on the sample drawer cavity at intervals not to exceed j six months. , !

All personnel involved in the use of the Gamma-Cell 40 unit, and its radiation monitoring, will comply with the provisions of the above regulations and procedures.
