I killed two birds with one stone\u2014I did a little studying and got some work-appropriate training at the same time!<\/p>\n<p>When you do get around to studying, you will discover that, according to the <a href=\"https:\/\/www-pub.iaea.org\/MTCD\/publications\/PDF\/Pub1570_web.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">IAEA regulations<\/a> (pages 62\u201363), the TI for a small package is determined by the following procedure:<\/p>\n<p style=\"padding-left: 30px;\">523 (a) Determine the maximum <em>radiation level<\/em> in units of millisieverts per hour (mSv\/h) at a distance of 1 m from the external surfaces of the package, overpack, freight container or unpackaged LSA-I and SCO-I.

We really only need the dose rate at 1 m of 43 \u00b5Sv\/h. (The other two dose rates have no bearing on the TI.)
