General Booth Guidelines and Appearance

The Exhibit Hall atmosphere must always be consistent with the educational mission of ASTRO. All booth activities and content must be professional in nature and provide educational information related to the field of radiation oncology.

Booth Carpeting

All exhibit space must be carpeted or covered with an ASTRO approved material. Bare floors in booths are not permitted. Carpet is NOT included in your exhibit space package and must be provided at the exhibitor’s’ expense.  Rental carpet will be available through the General Services Contractor (GES.)

General Appearance

Any booth bordering another exhibit booth must have the exposed back and side of that portion of the booth finished and may not carry signs or other copy that would detract from the adjoining exhibit. All exposed surfaces of the exhibit must be finished or may be masked at the discretion of ASTRO Show Management at the exhibitor's expense.

Inline Booths 

Regardless of the number of inline booths utilized, display materials should be arranged in such a manner so as not to obstruct sight lines of neighboring exhibitors. The maximum height of 8 feet (2.44 meters) is allowed in the rear half of an inline booth and a maximum of 4 feet (1.22 meters) in the remaining space forward to the aisle. No objects or materials that obstruct visibility will be permitted in the front half of an inline booth. Hanging signs are not permitted over inline booths.

Corner Booths 

All guidelines for inline booths apply to corner booths. Please refer to the inline booth requirements for more information.

Island Booths

Island booths must be constructed to allow access from all sides. Solid walls cannot span more than 30% of the booth and must have a 30% see-through effect from front to back and side to side, so that the surrounding area can be viewed around and through the booth and that neighboring booths are not inappropriately obstructed. Please note that opaque and/or frosted walls are not considered see-through. Any theater presentation or demonstration areas should be set back a minimum of 5 feet from the booth edge and allow adequate room for seating or standing without obstructing any aisles.

All booths that are 400 square feet or larger are required to submit a rendering of the booth with all necessary measurements clearly indicated, as well as any hanging signage, truss/lighting, suspended product, etc., for ASTRO approval, by September 13, 2021. Booth renderings must be submitted via the online submission process in the Exhibitor Resource Center. 

Island booths may not exceed 24 feet in height from the floor to the top of any structure or from floor to the top of any signage, unless approved in writing in advance by ASTRO Show Management. Any structure or signage exceeding the 24 feet height rule will be adjusted by ASTRO Show Management to conform with this regulation at the expense of the exhibitor. Towers and other components over 16 feet in height must be engineered appropriate to their use and constructed from drawings bearing the stamp of a reviewing structural engineer.  
*Exceptions may be made on a case-by-case basis due to federal regulations.

Enclosed Covered Booths

Covered or roofed areas must conform to the regulations set forth in the General Policies, Rules and Regulations of the McCormick Place Convention Center. The exhibiting company is responsible for any costs related to this requirement.

Multi-story Booths

Multi-story booths must follow the same rules as an island booth and must have a booth rendering with a stamp of a qualified structural engineer attesting to its construction standards. Any company constructing a multi-story booth must comply with the requirements set forth for multi-level booths in the MPCC Fire Department Regulations and submit an Architectural Design plan to the Fire Marshal a minimum of 90 days before the first move-in date for the event for approval.

Booth Rigging and Hanging Signage

All exhibits that require rigging, including but not limited to hanging signs and banners, structures, lighting and truss, must submit their rigging renderings to ASTRO for approval. Rigging renderings must be submitted via the submission process in the Exhibitor Resource Center. Please be sure to include measurements for the sign or structure's size as well as measurements for the exact placement within the booth. 

Hanging signs will only be permitted for island booths that are 20 foot by 20 foot or larger. Hanging signs may not block the visibility of ASTRO signs or other booths and should hang over contracted space only. Hanging digital signs are permitted provided that the images are static in nature and do not flash or move.


Island booths may use special lighting. All lighting must be directly over or in the exhibitor's booth and must not affect the aisle or other exhibitor booths. Exhibitors may request that overhead lighting at the McCormick Place Convention Center be blacked out to accommodate an exhibitor's specific lighting requirements. Such requests may only be made on-site by contacting ASTRO Show Management. All lights-out requests are subject to ASTRO review and approval. ASTRO will not approve any overhead lighting adjustments that may affect aisles or another exhibitor's space.

Flammable Materials

No flammable fluids or materials of any nature, including decorative materials, use of which is prohibited by national, state or city fire regulations, may be located in or used in any exhibitor's booth. For more information on fire safety regulations, view the MPCC Fire Department Regulations.

Electrical Safety

All wiring on booths or display fixtures within an exhibitor's booth must meet underwriters' rules and standard fire department inspection applicable under all appropriate state, county, city and McCormick Place Convention Center’s electrical and fire codes and regulations. This applies to booth construction only and not to pre-wired radio and electronic equipment. Visit the MPCC Fire Department Regulations for all fire safety, use of caution tape, cabling and other regulations related to electrical safety.

Flashing Lighting, Noise and Odors

Flashing or glaring lights, noisily operating displays, and/or exhibits producing objectionable odors will not be permitted in the Exhibit Hall. Sound equipment may be used in the Exhibitor's booth provided that the noise level does not disrupt the activities of neighboring exhibitors. Exhibitors using audio systems should direct the sound into their booth and not toward the aisles or neighboring booths. Sound levels should not exceed 85 decibels. ASTRO shall have sole discretion in determining what is noisy, obstructive and/or objectionable and take such action as they deem appropriate.


Any exhibitor using music must ensure that proper licensing fees have been paid to the appropriate agency, i.e., ASCAP, BMI, etc., by said exhibitor. ASTRO is not responsible for any licensing fees for music played in exhibitor's booth.


The use of music, dancers or mimes or other entertainment similar in nature is not permitted in the Exhibit Hall. Models that are professional in nature may be used for demonstration purposes within an exhibit but may not leave that individual exhibitor's booth space parameters to drive traffic to the booth and/or pass out information or take "polls".

Obstruction of Aisles or Other Exhibitors' Booth(s)

Any demonstration or activity that results in excessive obstruction of aisles or prevents ready access to any other nearby or adjacent exhibitor's booth shall be suspended by the exhibitor totally or for any specific periods as specified solely at the discretion of ASTRO.

McCormick Place Convention Center Fire Department Regulations

Please be sure to review the MPCC Fire Department Regulations for the complete list of rules for Exhibitors.

Violation of Exhibitor Rules

Should Exhibitor violate any provision of the Booth Equipment and Design Guidelines or the 2021 Annual Meeting Exhibitor Rules, Regulations and Policies, as determined by ASTRO Show Management in its sole discretion, including but not limited to giveaways, sound, entertainment, etc., ASTRO Show Management reserves the right to take one or more of the following actions:
  • ASTRO Show Management may give a verbal warning and ask Exhibitor to immediately cease action that is not in compliance with the Rules.
