THE CLAIM / RADIATION
Could anyone survive the radiation?
RECORD / AT A GLANCE
FALSE
Apollo crews crossed the belts in a few hours. Their measured skin doses averaged 0.46 rad, far below harmful levels. The real danger was a major solar storm, and Apollo was lucky to miss one.

NASA itself says the belts are a problem.
In October 2014 Orion engineer Kelly Smith said in a NASA video that the belts were dangerous and that “we must solve these challenges before we send people through this region of space.” If NASA still has to solve the problem, the argument goes, it cannot have done so in 1969. [1][2][3]

A dose problem, not a wall.
The belts are zones of trapped particles, not a barrier. The dose depends on how long you stay and how you travel. Apollo trajectories crossed them in a few hours, avoiding the most intense regions. [1]
Each crew wore dosimeters. Crew-average skin doses ranged from 0.16 rad on Apollo 8 to 1.14 rad on Apollo 14, an average of 0.46 rad; most of it came from passing through the belts. No crew exceeded the annual limit for radiation workers. [2][3]
Smith was narrating a video about an uncrewed test flight. The danger he named was to Orion’s “guidance systems, on-board computers or other electronics”, and he said sensors on board would record radiation levels for scientists to study before crews flew on the new spacecraft. [4][5]
What we can’t tell you. Skin dose in rad is not the same as whole-body effective dose.

A solar storm between Apollo 16 and 17.
The ALSJ review notes that the only solar particle event in the 1964–1976 cycle big enough to threaten an unprotected crew came on 4 August 1972, midway between Apollo 16 and 17. A crew on the surface could have received a skin dose of about 600 rem. [1]
NASA now plans radiation forecasting and shielding for Artemis crews. [2] Apollo’s safety record included luck.
