contamination in rm 128, Cherry Emerson Bldg.

The monthly research lab suveys were carried out in the Cherry Emerson of room Building (Biology Dept.) on Friday July 27th. The survey 128 revealed P-32 contamination at several spots on the floor, on attached survey the controls map) . of aAn centrifuge, and in the sink drain (see checked for contamination and individual working in the room was discernable from background) had very low levels of P-32 on her shoes. The shoes (werejust decontaminated by radiation safety staff and returned to her.

Other personnel who work in the area were checked for contamination and none was detected.

waste containers and accumulation Also observed were unlabelled radioactive dose rates. of waste causing high ambient 1 Room 128 is used jointly by research staff under Dr. J. Choi P' and Dr. Dwight Hall.

pointed out our survey findings.

I spoke to both individuals on Friday and At that ti.me I asked that work be discontinued and the room was posted as a " Contaminated Area" and locked for the weekend with rad. tape over the door.

On Monday Rodney Bauman and myself performed a complete decontamination of the room. Floors counters and equipment were cleaned, radiation work areas were se, tup with spill pads and clear radiation markings, rad. waste storage areas were setup and all accumulated the requirement wasteto was removed and new containers supplied. Also, doorway. " Frisk Upon Exit" was posted at the room Tuesday, a meeting was held in room 128 attended by myself, Rodney Bauman. , Drs. Choi and Hall and six graduate student workers who use the area (signcture sheet attached). I reviewed the problems found in the lab and gave instruction in methods of contamination etc. control, regulatory requirements, monitoring methods, Drs. Choi and Hall outlined new procedures for keeping the room organized and clean and controlling waste accumulation.
