The concept of "'effective dose "'was developed by Wolfgang Jacobi and published in 1975, and was so convincing that the ICRP incorporated it into their 1977 general recommendations ( publication 26 ) as " effective dose equivalent ".

Area dosimeters or dose ratemeters should be calibrated in terms of the ambient dose equivalent, H * ( 10 ), or the directional dose equivalent, H2 ( 0.07 ), without any phantom present, i . e . free in air ."

"The quantity dose equivalent " H " is the product of the absorbed dose " D " of ionizing radiation and the dimensionless factor " Q " ( quality factor ) defined as a function of linear energy transfer by the ICRU"

The dose measurement quantity, personal dose equivalent Hp ( d ), is defined by the International Commission on Radiological Protection ( ICRP ) as the dose equivalent in soft tissue at an appropriate depth, d, below a specified point on the human body.
26.
Prior to 1990, the ICRP used the term " dose equivalent " to refer to the absorbed dose at a point multiplied by the quality factor at that point, where the quality factor was a function of linear energy transfer ( LET ).

The dose measurement quantity, personal dose equivalent Hp ( d ), is defined by the International Commission on Radiological Protection ( ICRP ) as the dose equivalent in soft tissue at an appropriate depth, d, below a specified point on the human body.
28.
The ICRP states that if a personal dosimeter is worn on a position on the body representative of its exposure, assuming whole-body exposure, the value of personal dose equivalent Hp ( 10 ) is sufficient to estimate an effective dose value suitable for radiological protection.

Based on these measurements, for a round trip Mars surface mission with 180 days ( each way ) cruise, and 500 days on the Martian surface for this current solar cycle, an astronaut would be exposed to a total mission dose equivalent of ~ 1.01 sievert.

A toxicology study in rhesus monkeys resulted in the death of all rhesus fetuses exposed to 1 and 10 times the human dose equivalent of OHPC ., OHPC was a category D progestin according to the FDA ( that is, there is evidence of fetal harm ).
