Answer to Question #104 Submitted to "Ask the Experts"

Category: Environmental and Background Radiation — General

The following question was answered by an expert in the appropriate field:

How I can have data of dose and kind of particles in normal and spatial flight?

Information regarding doses and radiation fields can be found in the following sources:

Terrestrial sources and doses—NCRP Report Nos. 93 (Ionizing Radiation Exposure of the Population of the United States), 94 (Exposure of the Population of the United States and Canada from Natural Background Radiation), 95 (Radiation Exposure of the U.S. Population from Consumer Products and Miscellaneous Sources), and 100 (Exposure of the U.S. Population from Diagnostic Medical Radiation).
Space Radiation—NCRP Symposium Proceedings No. 3 (Acceptability of Risk from Radiation - Application to Human Space Flight)
Commercial Aircraft—NCRP Commentary No. 12 (Radiation Exposure and High-Altitude Flight).

Note that the Proceedings of the 1998 NCRP Annual Meeting, when published, will contain more up-to-date information on space and aircraft exposures. For information on ordering NCRP publications see the NCRP Web site.
