Introduction to nuclear medicine technology NMT 231

Hot Lab

• nuclear medicine facilities are divided into two parts:-

i) controlled area ii) supervised area. • Hot lab is named as controlled area/room

Hot Lab

• Hot lab is a specially designed room in a nuclear medicine

hospital where the radiopharmaceuticals are delivered, stored and

prepared for dispensing.

• The workers spend most of their time for patient dose preparation.

• All the nuclear medicine facilities in the World use some common

radionuclide such as 99mTc, 131I, 125I, 129I, 137Cs, 90Sr, 32P,

57Co for calibration, diagnostic use and therapeutic modalities, as

well as academic and research activities

• Syringe and Vial Shields• Shielding & Storage Products• Dose Calibrators and Wipe Test Counters• Sinks and washing facility

Building requirements

• Floors Impervious materialWashableChemical-resistantCurved to the wallsAll joints sealed

Worktop surfaces

• Worktop surfaces must be finished in a smooth, washable and chemical-resistant surface with all joints sealed. Some laminates do not resist certain chemicals, and the supplier should be consulted with regard to the specific chemicals to be used in the laboratory.

Part 4. Design 7

Worktop surfaces

Cover the surface with absorbing paper

VENTILATION

• Laboratories in which unsealed sources, especially radioactive aerosols or gases, may be produced or handled should have an appropriate ventilation system that includes a fume hood, laminar air flow cabinet or glove box

Sinks and washing facility

Part 4. Design 10

Washing facilitiesThe wash-up sink should be located in a low-traffic area adjacent to the work area. Taps should be operable without direct hand contact and disposable towels or hot air dryer should be available. An emergency eye-wash should be installed near the hand-washing sink and there should be access to an emergency shower in or near the laboratory.

Safety equipment in hot lab

• Shields

• Protective clothing

• Tools for remote handling

• of radioactive material

• Containers for radioactive waste

• Dose rate monitor with alarm

• Contamination monitor

• Decontamination kit

• Signs, labels and records

Shielding

• Bench top shield

• Vial shields

• Syringe shields

• Structural shielding

Containers for radioactive waste

Several containers should be availablein order to segregate the waste atthe point of origin (radionuclides, half-lives, glass, paper, syringes etc.)
