5.10.4 CUBICLE CURTAIN TRACKS
Do not use cubicle curtain tracks in patient bedrooms of Mental Health and
Behavioral Nursing Units.
5.10.5 PATIENT TOILETS AND BATHROOMS
5.10.5.1 The VA Equipment Guide List call for grab bars in all Psychiatric
toilets and baths, although the Uniform Federal Accessibility Standards
requires only 10% of them to be so equipped. For areas to be used by high-
risk patients, "institutional grab bars are available with a continuous
flange, closing the space between the bar and the wall.
5.10.5.2 Mirrors in Mental Health and Behavioral Patient Care Units should be
heat tempered glass; see Equipment Guide List, Chapter 110.xls.

5.11 RADIATION THERAPY
5.11.1 GENERAL
5.11.1.1 Radiation therapy
employs high
energy X-rays,
gamma rays,
and
electron beams to treat tumors and other malignancies. This radiation is
generated by devices ranging from 50 kilovolt X-ray units, to supervoltage
units (Cobalt 60) for gamma rays, to linear accelerators of more than 10
million electron volts.
5.11.1.2 The more powerful units usually require shielding by concrete vaults
with maze-like entries.
5.11.2 SHIELDING POLICY
Provide shielding as prescribed by a physicist, approved by the American
Board of Radiology in accordance with the appropriate standards and
regulations contained in Report No.102 of the National Council on Radiation
Protection and Measurements, obtainable from NCRP Publications, 7910 Woodmont
Avenue, Suite 400, Bethesda, MD-20814.
5.11.3 SPECIFICATION OF PROTECTIVE SHIELDING
State the prescribed shielding in terms of millimeters of lead or in
millimeters (in.) of wall, ceiling, floor and door construction of equivalent
protection thickness.
5.11.4 CERTIFICATION
Post a certificate, stating the lead equivalent protection of each surface,
in all rooms with radiation shielding.
5.11.5 DESIGN
5.11.5.1 See Space Planning Criteria, Chapter 277, "Radiation Therapy
Service" for space requirements, operating rationale, and design
considerations.
